Hi, if you're interested in a C# implementation of the Akismet Client Library, have a look at my blog at http://www.arnebrachhold.de/2006/04/18/akismet-anti-spam-library-for-the-dotnet-framework It's build with .Net 1.1, but should work in 2.0 without problems. Available as source or .dll. Best regards, Arne Brachhold
