Just wanted to mention to new keyers: I've always seen mention of "review the Wiki" -- but at first I missed the fact that at the top of the Wiki there is a tab labeled "discussion". This tab contains comments from reviewers regarding the most common keying mistakes. This is really helpful stuff! I used to review these message boards and the first Wiki page completely, but I missed the fact that this information was available for each project. To me, this is REALLY useful. I've caught myself in a few keying misconceptions this way.
