You have to draw the line somewhere!

Let's grow up, moderate our own forum and
save Richard time, money and bandwidth. For example:

Let's Talk 500 - hosted by Forumer
Play 500 - hosted by Google Groups

Either example could be owned, managed and moderated by the JG500 moderation team on behalf of the membership. Both could be integrated into the existing JG500 site. Neither would require any work by Richard. Both are free. Both offer features the current forum does not have: extended profiles, personal messaging, file uploads, embedded pictures and videos etc.
