Just to second some of what J.E. Sawyer had to say. The suggestions that have left the biggest impression on me are from people that are at least being polite. And it's funny how the equivalent of forum footnotes have some real great stuff to them. I have a medium think hide (giving me a +3 to my AC, woot! Pity about my armor check penalty, though) so I can take the stings of the board trolls. But I routinely gloss over some folks' feedback because they have been very negative and have established an unproductive reputation in my mind. And that's probably a charitable assessment. At the end of the day, if there's an idea someone loves their best bet is a cogent argument and a polite demeanor.
