One issue we are having on one of my sites is if the user is 18, 28, 38 etc...
it says something like Age 18) and the 8) gets transformed to

type smiley.
I couldn't figure out how to get around this, so I set up a new account to post the b-day messages and put them into a new usergroup that is not allowed to use smilies.... hoping that will fix it.. but no one has a 8 year b-day this month now =P
Well, anyone have any better ideas or have run into this issue before?
