I got some requests on having chat sessions from time to time. Because we didn't searched for a good chat application we are using http://treehouse.ofb.net/chat/ ?lang=en for a first chat test today:
The next chat will be using a .NET 2.0 Ajax.NET Professional example at http://chat.schwarz-interactive.de/ . Currently I have there an old version installed with the memory leak. Maybe I have enough time to upload the latest build there until this evening.
