OK folks, Excel 2007 is winning by ONE VOTE!!!
Access 2007 is a close second, and surprisingly, Access 2003 Advanced Lessons is right behind that.
So, all you Access fans, if you want to see more Access tutorials next, make sure to visit the WAITING LIST and cast your vote NOW.
I'll be starting the next class TOMORROW, based on the votes. As of right now, it looks like I'll be pulling the Excel books off my shelf.
