Can anyone tell me of some cool user name styles other than text shadow, glitter, image next to name, etc.
Do what it says to view the page obviously. I had no issues with it when I'm not a member.

There are no cool username effects.
[b][/b] or [i][/i]
are awesome, also [color=<colorhere>][/color] are good ones, would refrain from the rest.
Why would anyone want this?
You can do some cool effects with semi transparent images if you have a nice dark reddish purple background.
Otherwise it's just for show. IIRC my old titles had flames.
