I think I've taken care of the 3 items I was concerned about:

Attachments are disabled. Several of the file types allowed by default can carry viruses, and I don't want to be in the business of delivering them.

Smilies were already allowed -- you have to selected the "advanced" editing options or just type them in-line.

"Junior member" and "member" designations are gone. "Senior member" is retained for those with 150+ posts. Might as well reward those who stick around.
