For the last couple months, I was working on a feature to enable bug reporting on MSDN Forums. Last week we have started a pilot program with Visual Basic team and enabled bug reporting on several Visual Basic forums. Bug reporting procedure is very simple and all you have to do is select "Bug Report" while create a new post under an enabled forum and Microsoft will respond to your bug similart to other bugs submitted through Microsoft Connect. We believe having bug reporting integrated in MSDN Forums will make it much easier for people to submit bugs and also it will make resolutions, workarounds to the bugs much more visible.
You can find more detailed information related to the pilot program at Visual Basic team blog.
