I've pruned the forum of users who have never posted anything. I've kept users who have registered not more than three days ago.

If you want to have an account here post something or why would you want to have an account here anyways?

I'll also delete postings which simply say anything just so that there has been a posting. I'll also take the liberty of removing such users since they obviously don't come here to seek technical advice - which is a major goal of this forum. Any posting that looks like hidden spam (like a placeholder posting to enable an advertising signature in the future) will get removed together with the account! In some cases when I'm not entirely sure I use to give a warning in the respective forum thread first.

Feel free to re-register if you feel that your account has been removed without proper cause. It's free after all.
