Two suggested improvements
 

1. If possible, make the Smilies selection area scrollable so that one doesn't have to click the "Get More" link.

2. Create a facility under MyS2000 that would allow members to create a "Post Search Profile". This profile would consist of search terms such as those that you might enter on the Advanced Search page. Then whenever someone enters that combination of terms in a new post or post reply, the member, as the profile holder, would receive an email with a link to that thread. You could allow members to create multiple profiles and on a list of his/her profiles there would appear a check box next to the name of each profile so that the member could activate/deactivate any of his/her profiles at will.
