BB-Code in Signatures?
 

Not sure if this is an option with this version of phpBB or if it isn't available, but I think some bb code in signatures would be nice, for example, on other forums I use the [ small ] tag to make the text in my signature smaller since it isn't overly relevant all the time... (or the size tag if small isn't available)

I'll check the server configuration. I believe it may be doable.
