Welcome to the CCL Website!!!

The Computational Chemistry List (CCL) was established on January 11, 1991, as an independent electronic forum for chemistry researchers and educators from around the world. If you want it to continue, please support it with your participation in discussions, contributing files to the CCL archives, use of its paid services and becoming its supporting member.

Remember to take a look at our POSITIONS OPEN (CCL Jobs) page

It is estimated that more than 3000 members in more than 50 countries are reading CCL messages regularly. Normally, the traffic does not exceed 20 messages a day. You can examine all past messages.

The discussions cover all aspects of computational chemistry; however, before posting, contributors are asked to read the instructions and regulations. Please SUPPORT CCL to ensure its continuing service to the community.

If you have problems sending regular email to the list of subscribers or to CCL administrators, please tell me about it by using a secure form at Email To Administrator. Tell me about your problems. CCL is under constant attack from the scam of the Internet and gets 10k spam messages a day. It is also under constant break-in attacks that go in thousands a day. My server usage shows that it spends 99.99% of the CPU processing these threats. By necessity, I had to install very broad spam filters and your regular email is oftern rejected or even worse: it goes to a junk bin without telling you or me about it. If I was rejecting the spam, I would be spamming innocent victims whose addresses were used on the From: line by the scum or the Internet. Again, tell me about your problems, by including bounce message headers and the bounce text in the secure page above.
However, it will take me some time to look at your message. If you need to send email to CCL members pronto use the CCL MAIL WEB FORM. It skips some (but not all) aggressive spam filters. If your email bounces from the ccl.net domain with the 5.7.1 error, please read the: spammers.txt for more information and send me a message via the Email To Administrator form.
I am sorry, but I am not sure how long I can run the CCL Forum. I cannot get any help, since the income from banners and job ads barely covers the physical costs of running the forum. At the same time I have to support my family with the full-time job (usually 1.5x full time job, since the 8am-4pm jobs do not come my way {:-)}).
