Rutteger, I can imagine all the work a site like this demands, so I'm also confident that it's easier said then done. I would really like to see G-SZ become a prime place for g-shockaholics to hang around to talk and learn about G, and I'm positive that all collectors and enthusiasts would be interested in seeing that. Right now G-SZ has a very small traffic, which won't bring many discussions and therefor cause a general lack of content. What we do see now is almost only For Sale adds, and I'm probably not the only one that gets a bit bothered by that, specially if these adds are almost 100% by "professional" sellers and not collectors/enthusiasts. I'm afraid that many enthusiasts get chased away by that, maybe feeling that the forum is one of those "direct sales" places that have been all over the web.
Unfortunately this can happen to any hobby site/forum, and what could avoid this is to put a minimum number of posts before you can visit and post at the sales section. Of course this could cause these "professional sellers" to try to flood the boards with posts to get their post count up, but that kind of behavior is easily adjusted by a good moderation team. Many forums use that policy and at least at the ones I visit regularly it seems to work.
