Since the SharePoint 2007 products (WSS 3.0, MOSS 2007, and SPD 2007) released about 11 months ago, there has been a tremendous amount of Q&A and discussions in numerous blog comments, in several major public e-mail distribution lists, in a handful of newsgroups, in dozens of web forums, and in countless private corporate e-mail distribution lists. From what I can tell though I must admit that I haven't done extensive research, there's quite a bit of duplication in the topics being asked about or discussed.
Forums to the rescue! And now there's a friendly URL for you to get to them much more quickly: http://mssharepointforums.com.
