If someone had a signature that could be deemed as offensive how would you report it, pm them and ask them directly or through a mod?
 
Im sure a PM would be the 1st port of call, at least they cant complain when you email a moderator if no joy.
 
Hi,
I have hit 15 posts and still can't find the signature bx in the user section. Am I doing something wrong ?
Cheers
James
 
You need to give the server time to update your user status as it's not instant.
 
You'll need to wait for the server to update which can take up to 24 hours if some of your posts have been made today.

Failing that it may have changed to 20/25 posts.
