If one posts a question here that concerns the usage of Regular Expression in .Net and it goes unanswered due to the question needing .Net specific knowledge, one should post it to the MSDN Regular Expression forum that has recently been created. Or please recommend the user go there for such advice. The tagline for the forum is

    Discuss and ask questions concerning the usage of Regular Expressions (REGEXes) in the .NET Framework.

I am one of the many moderators on the MSDN forums and for those not familiar with the MSDN forums, it not a direct conduit to Microsoft support, but to forums, hosted by Microsoft, where posts go to people that are primarily non-Microsoft volunteers, such as myself. There are MS employees from specific development groups which do answer on a frequent basis when questions go unanswered or the posts need specific technical expertise. There are also MVPs, again non-MS people, who have been designated by Microsoft for providing outstanding support to the technical community in a certain technological area, who have demonstrated expertise in that field who answer as well.

The goal of this post here is not to compete but cooperate. I have used RegexAdvice and recommend it to other users. It provides needed help for regex specific questions for the many different flavors of regex. But it does not necessarily provide MS specific advice, to which I don't blame them. I run Unix website and Perl is one of my favorite languages, so there is a time and place for everything. I plan to add a reciprocal link inside the MSDN Regex forum on one of the top level announcements to RegExAdvice for true regex questions.

One will need to have a passport/Live ID to logon, but if one has development questions, even outside regex, the MSDN forums is an excellent place to post and learn. See the top level list of forums here.
 

Thanks For your Time.
