Have you thought about making a NuGet package for SgmlReader? It'll make it a lot easier for people to start using the library. I'd be happy to create one for you and post it to the feed to get started.
If you haven't heard of NuGet, please check out my blog post here: http://haacked.com/archive/2010/10/0...e-manager.aspx
and the CodePlex website - http://nuget.codeplex.com/
If I create one for you, should I simply list "Mindtouch" as the author?
