Upgrade sounds good! Sounds like a lot of work, but if it keeps members from being booted on the whims of whoever gets there first (a complaint I heard from a few of our members) I'm all for it!
I was sorry to hear that IW's chat room was used to make disgusting comments and derogatory statements as well.
I know a few members were so put off they left the chat after signing in for the first time.
Can't wait to see the new version!
