A friend of mine, and a fellow MCT, Mattias Lind have launched a forum about a month ago. In his forums you can discuss everything about SQL. The forums are not so big today but I think that as everything Mattias does it will be very good. Go there with your questions and I’m sure you will get some great answers!
