A Funny Thing Happened on the Way to the TechNet Forum
Forums (fora for Latin geeks) date back to well before Microsoft and even Frankie Howerd.
TechNet has a raft of forums on almost every Microsoft technology as it affects IT professionals where you can get and give help. Both MVP's and Microsoft product guys keep watch on these so you can usually get a good answer within a day or so of posting your question.
New forum topics are popping up all the time and I have just spotted two new Performance Point forums here
If you need a technical answer in a hurry then I would recommend a TechNet subscription which gives you 2 support calls a year per subscriber on top of what else you might have in place in your organisation.
