Just a quick update that I'll be purging 248 in-active accounts over the next week and I'll probably be performing an upgrade to SMF 2.0 RC4 (we're currently running SMF 1.1.12). We'll probably run with the default theme for a while we'll I figure out which theme works best for this site.
I've noticed that a large majority of the in-active accounts appear to have been used to try and harvest our registered users' email addresses, IM handles, etc. I'm hoping to create a new security group to restrict access to view such information until a user has made a legitimate post or until the user has been manually upgraded by a moderator.
Cheers!
