I am running firefox 6 on an xp box and have very long load times for all pages and chatbox.
Alright - the site has been moved to a brand new server and also upgraded to the latest version. Hopefully the slow access and chatbox issues will be reduced or eliminated now.
Please if you have problems with anything let me know here. The more detail you can provide the better (What browser or browser's were you using and as much detail as possible about what the issue is and how you got to the point where something didn't work or failed, etc.).
