Microsoft Answers: The PowerPoint Support Forum (and the former PowerPoint newsgroup, etc.)
There's a group of friendly people who'll answer your questions and help solve your PowerPoint problems. All you need to do is ask.
Politely, please. For the most part, they're volunteers, not Microsoft employees. Rudeness is probably the best way to get yourself ignored. 'Nuff said?
Where can I find them?
Visit the PowerPoint section of the Microsoft Answers forum
Anyone can read the questions and answers there but to ask or answer questions, you'll need to be using a supported browser and you'll need to sign in using a valid LiveID (aka Net Passport). If you don't have one, you can create one from the sign-in page.
