Dear CCAlive user,
This website has become more popular than our web server is able to handle efficiently. Although this is a good problem to have, it also means major upgrades are required for which we need your support.
Over the past week a handful of generous people have come forward to contribute, which makes me optimistic that more of you will soon follow. With this continued support, I'm looking to have the server upgraded by mid-March.
To encourage more people to help out, registration will begin once the new server is up and running. Notably, site registration will remain free of charge. As always, your contribution is voluntary.
Please consider supporting this website for the value you receive from it. Click here to contribute any amount. For $15 I will also send you a copy of my detailed Chapter Summaries, which students tell me they find very helpful.
Good chemistry to you,
John Suchocki
