Glad you got it sorted out as you made it sound like it was my problem
I do use an external chat server now but the interface to it I control 100%. When people login and out all day long with no problems and then someone complains of problems why they can't, the answer is simple, it's isolated to the user's computer, not the website.
Saying that, yeah, java isn't always included in every browser which is why I have the test java section and the links to download update.
Good to see your back on MACCA-Chat.
