[Xenon]

Ok i'll describe it a bit more:
User can create their own postbit, just they can use it then.
Before they can use it it needs to be validated by an admin.
As already said, there have to be some parts in it like $username aso.
Also i have made a small checkroutine so the cannot use <script>-tags.

it's planned to add an option for user not showing any custom postbits in threads.

also as all hacks this one would be customizable so if you just want to allow mods a custom postbit you can add a small if clause...
