How can I develop an instant messaging system for my website?
I would download the free “Visual C++ 2008 Express Edition”, and simply create a program, which handles the messages through http requests (considering that the messenger might be a part of the actual site aswell). The program/client could be available for your users as an optional download, or an alternative way to message each other, while not on the site. Actual messages would still be available through the website UI. You could even get more or less techinical, by simply making a plugin for one of the existing messenger clients, msn; aim; yim; icq; (Or perhaps better) Trillian. This may encourage your users to download, and install the plugin, i supose msn is the most used messenger client at the moment.
