After looking deeper into the MSDN Forums Client and into an C# NNTP server, I decided to integrate both Ms-PL projects into a single project:
The result is a single “Community Forums NNTP Bridge” which can replace the MS NNTP Bridge. It also integrates both web services (*social*, *answers*) into a single NNTP server; so the “feeling” is like before the split 😉
If you are interested, you can take a look (with full source code) into the alternative:
