The first time you use chat room, you have to register as a chat room user, you cant use the same log in pass etc as logging into the forum. I'm osrry to sound so vague, but if you go click onto the chat room button or the panel at the left hand side of the page from the arillas home page, it will take you to the whole set p of the chat room and instructions should be on there.
Hope this helps, It was a while ago since I registered so I have forgotten since then, bit if I remember correctly it was all quite easy to follow.
As before, any problems - email Dimitris, he will help you along the process - he is so acommodating.
