I was active on a UBB forum years ago. I enjoyed the layout and am seriously considering a "forum dot" subdomain for my site with a UBB.
For nostalgia:
The "off topic" area of that old forum adopted the old three question mark confused smiley as an unofficial mascot. One even had a die cut vinyl sticker made for his car.
Confused smiley was "Srs Bsns", to use Internet vernacular of the era.
I see the current confused smiley looks like this:

How difficult is changing the smiley file to use the old one? Or if I buy a license, can I use an older version of UBB that already has the smiley?
