Are you going to nominate yourself to figure out which ones are seldom (if ever) used?
I suggested getting rid of some smilies awhile back and it was shot down.
If we just get rid of/delete some, though, there is the potential for weird posts that were made in the past. Which is why I suggested replacing some of them.
Since there's already "clutter" by the Reply box, what's it matter if there's a bit more?
