Seems to work okay on other forums mate.
The rule is, you can't make it up with spam posts or you get banned. Pretty simple really.
Surely when people join, a little email from Edd goes out to them welcoming them onboard etc? In that email should be a link to the forum faq, one would think.
If you can't give twenty quality posts...
Here is some help for people having trouble working out how hard it is to get twenty posts.
5-10 posts...Introducing yourself and saying hi.
1-5 posts....Checking out a few of the limelights.
1-5 posts...Bumping old posts they think they can contribute too.
1-5 posts...posting some pics of your own collection in the limelight section and talking about it.
Posts like "awesome", and "great" should not count towards your post count initially, and so should be removed.
Thanks for listening anyway, Weas.
