Looks like Steve found a way to host chat externally, it is linked now on the GS site:
http://golfseeker.co.uk/main/gs-chat.html
That opens an instant messenger application, which you have to register for. Then look for the 'chat rooms' option (right under the 'go' button). Gonna be a bit different, but at least we have live chat again!
Hopefully Steve will post an update in the latest news so we all know what the heck happened, and who ruined this for us......
