Because there are a lot of developers frustrated by the license of the BorgWorX Ajax.NET source code I will help  you how to use the source code in your environment. If you send me your email and mailing address including company name you will get a license to use the Ajax.NET source code in your projects. The only thing you have to do is: send bugfixes or new features (C# source code) to one of the authors email address or using SVN (account needed first). You are not allowed to create a standalone AJAX library with the Ajax.NET source code. Build your own controls using the powerful Ajax.NET library.
