Forum Signature limitations
 

Hi all,

there was the problem, that some users have very "stylish" signatures. Inverted or other stuff. Like this:

Is there any aproach to allow only a-z 0-1 - or like an array of allowed characters? Limitation to a simple charset maybe?
The solution should keep the already existing 56404 signatures alive - btw ;)

greets, Nik
