Good ideas all.
I just added a table of contents to the troubleshooting guide and moved some of the more common questions to the top. I hope this helps people find answers to their questions. If you have any other suggestions for that page (e.g. other things that should be listed), please let me know.
I think the sticky's could be good too, but I'm not sure how much gain we'd get (are the people who don't Google for the answers likely to read a sticky?). What about just putting a sticky in the two troubleshooting forums pointing to the troubleshooting guide? The rest of your suggestions are excellent, but I'm not sure where to put them. They seem to apply to the entire forum, but I'm wary of putting a big block of text at the top of every page (or even the bottom of the "Post Reply" pages). Thoughts?
