Over the pastfew week Microsoft has been updating many of their forums. For those not familiar Microsoft host the MSDN forums so that those working with related technologies can communicate and ask each other for assistance. The Smart Device Development forums when through their metamorphosis last week. While there are still a few things transitioning over the migration of the core information and functionality seems to be complete. The interface of the new forum is more aesthetically pleasing and much more responsive (it is based in Ajax) and the editor is much easier to use and gives more control over formatting.
If you are ever stuck with a problem that you cannot figure out then this is always a good place to start. However the promptness and accuracy of your response is going to be dependent on the clarity of your question. So if you've never posted in a newsgroup or forum before I'd like to direct you to some general rules that Daniel Moth wrote that will help ensure that you get the best answer.
