Well, you could go to the JavaRanch forum, and put in a plea to
Paul Wheaton. I really don't know what the UBB software will allow in this department.
On the other hand, you could always join
COPPWUUN (the "Committee On Persuading
Paul Wheaton to Upgrade UBB Now") and see what fun things are in the next version of UBB (that would be 6.0)
