thanks, but we may not be out of the fire yet...
One of the things that may have been causing the login problems is an applet we use to allow users behind a firewall to access the chat. I removed it, and now we seem to have better luck logging in. We'll have to replace it soon, though, to allow our guest speakers (who often connect via their corporate access) in. I've spoken with our vendor and they should have this applet installed and working on their servers hopefully today...
thanks for your patience and feedback...
