Here is good a list of resources, forums and tutorials for people learning about Microsoft Excel (especially Office Excel 2007).
www.MrExcel.com/forum: for direct help in a forum environment The Mr.Excel forum is run by Mr. Excel (Bill Jelen), another Microsoft Excel MVP, and author of several Excel books. MrExcel.com is the pre-emininent Excel help forum out there, with over 1 million posts since its inception. Smitty can be found on the Mr. Excel message board/forum under the username “Smitty” (how original). Please join, log in, and ask your questions!
www.peltiertech.com: Excel Charting. There is no better charting wizard in the world than Jon Peltier, Excel MVP…
www.cpearson.com: Excel MVP Chip Pearson’s Excel Tutorials (Advanced). He is has a knowledge base of his own that leaves many helpfiles lacking. He was also one of the first Microsoft Excel MVP’s.
www.contextures.com: Excel MVP Debra Dalgliesh’s Beginner (and advanced) tutorials.
www.vbaexpress.com: Excel MVP Zack Barresse’s VBA Programming message board/forum. (There are some VBA training modules there too…)
www.fontstuff.com: Martin Green’s VBA Tutorials (among other things). Make sure to check out his Calendar Control tutorial!
www.theofficeexperts.com: Word MVP Anne Troy’s message board/forum for other Office Programs (Word, Outlook, etc.). I go there for my Word questions.
Silicon Valley Excel Users’ Group: a group I set up on LinkedIn to represent, well duh, Silicon Valley Excel Users. I hope to be able to generate some interaction between SV Excel users, especially as there are several Microsoft Excel MVP’s in this neck of the woods. If there’s enough interest we might be able to get Microsoft to host some meetings and possibly provide some product giveaways. Please join if you’re interested!
