I hope nobody minds one of the "new guys" making some suggestions to save space, although I fear that some may be unpopular. I think that the following are "nice to have" features, but not essential to keep this message board going.
Eliminate older threads that are no longer active, even if they have been answered. Is someone really going to go back more than a year, or so, to read them? I doubt it.
Eliminate "SpellCheck". You can either put a dictionary next to your computer or use this web site.
http://www.spellcheck.net/
Eliminate "signatures". I don't feel that they add much. At least the avatars give the site some character.
Eliminate the "private messages" feature. If one doesn't want to communicate with your regular email address, use a web-based one like Hotmail.
