The efforts to improve the e-mail services provided by our university has now matured, and as a consequence of these newly adopted improvements by METU CC on central Unix servers which serve 24 hours and 365 days, the e-mail addresses which belong to the students, the academic and administrative personnel, have been changed with a continuous effort to usernamemetu.edu.tr since the process was launched in April.

Due to the insufficiency of the ULAKNET connections which connect the academic institutions and since TTNET connections are now made available, the investments have been made to connect METU to this network structure. In this respect, the 34 Mbyte/sc connection between the Balgat switch and METU, has been activated after the necessary configurations are completed. The capacity of ULAKNET connection has been multiplied by 4 Mbyte/sc via adding a 2 Mbyte/sc connection. Providing an additional TTNET connection with a capacity of 8 Mbyte/sc , these recent efforts have accumulated to a total internet connection capacity of 12 Mbyte/sc. To answer the intense demands of the the users and to offer a problem-free service, investments are being made to build ISDN/PRI MODEM connections of digital technology with a capacity of 60 lines.

3 new laboratories serving for multimedia purposes have been built within the project called BADE to facilitate the learning of basic package programs by the prep school students and freshmen. As a consequence, the total number of the PC rooms is now 16 and the total number of the PCs in these rooms have reached 423.

Within the framework of the agreement which is entered into with Yildiz University and Hacettepe University in 1997, the projects of automation have been carried out , new programs for the specific needs of university have been written and they are now being used. Later in time, after some alterations and regulations on these projects, a package has been developed to build Registrar's Office Information System(OİBS) project. During spring semester grading period, this system has been started to be used in our university.

The Circulation Module (Lending books) of the VTLS System is now available to all library users. Therefore, the library's card system is now being gradually abandoned.

11 educational seminars particularly concerned with the users were held and a total of 1242 people had participated in them. The booklets "Temel Bilgisayar Kullanimi", "Introduction to SPSS" have run out of the available supplies, therefore they are updated and republished with the latest information. There are endeavors engaged in under the topic of Quality Improvement Project and the hot-line service offered to our users is chosen as the pilot project.

The restructuring and the renewal of the design of METU and CC Web Pages, which are accessible within METU-CWIS, are initiated. The electronic List Server (listproc) which is running on central servers, is also built as a new web page with its address as metu.edu.tr/list_server , for it would facilitate the accessibility to information on the List Server. The service of METU Newsgroups are still carried out on the related server which is bearing 7579 newsgroups.

Within the scope of the endeavors to cope with the Y2K problem, the inventories of all of the software,hardware and embedded chips have been made and the compatibility of all of the systems in the inventory with the Y2K have been tested. "Unexpected Inconvenience Plan" has been prepared to prevent the handicaps which may arise in between December 31st and January 2nd and to keep our users away from the effects of Y2K problem.

2000 8 seminars under the topics such as Windows, UNIX, MS Office, Photoshop, Internet, Temel Bilgisayar Tanitimi, Lisansli Yazilim Tanitimi, Ansys Yazilim Tanitimi were held. A total of 1.091 people (Academic and Administrative personnel, Students, PC Operators, Teachers of the schools which are within the scope of Contribution to 8-year Education Project, participants from TRT (Turkish Radio Television) and Ministry of Education) have participated in the seminars.

The "webmail" service, which enables users to access the electronic e-mail service on the central servers through a web browser (Netscape, Internet Explorer, etc.) from either inside or outside METU, was provided at http://webmail.metu.edu.tr at the end of a preliminary tests and long pilot application period.

The planning phase of the METU wireless networking project was launched in 1999. The required devices were purchased consequently and the first pilot application process was carried out throughout April of 2000. Campus backbone network access of Sports Hall, METU-MET, Psychological Counseling and Guidance Center, were provided over wireless network within the scope of METU wireless networking project.

As soon as all the units that were connected to Token-ring were completely transferred to ATM backbone, the token-ring backbone was closed at the beginning of the year 2000. This increased the number of units/departments that are connected to ATM backbone to 90. Moreover, a total of 16 units were indirectly connected to the ATM backbone network via applying ethernet technology.

METU web pages, which were started to be used in 1994 as pilot application, were revised content wise and as respects to its design in 1997. Lastly, on November 6th, 2000, the site was reintroduced to users as of two sites, one in Turkish (www.odtu.edu.tr) and the other in English (www.metu.edu.tr). During the 2000-2001 Fall Semester Registrations, a "Registration Booklet" was prepared and the booklet was made available online. This process constitutes a novelty in regard to the former registration periods. Another new implementation i.e. providing important news and information about registrations over METU Wap site (wap.metu.edu.tr) was launched at the same time.

Computer Center's Library Services Automation Project was launched by on June 15th, 2000. In December 2000, the project was completed and the program was implemented as pilot application in METU CC.
