I've seen this on other forums, and I thought it looked good.
There is a bar underneath the Avatar which proclaims your level, which changes with post count. For instance, 0-10 posts- Noob. 10-50 posts- Beginner, 50-100 posts- Familiar, 100-250 Regular, 250-500- Expert, etcetera etcetera, new title for every 1000 or so. I think it would be a good way to subconciousley get users to post more regularly.
So what's the verdict?
