Well at last I managed to get it done. I have added a chatroom to the Forum. It is called Addon Chat and is situated at the very bottom of the Forum front page under all the footers on the page. It runs on Java so may ask you to install it, it also asks you if you wish to run the software, and will do this every time you go on the page unless you tick the little box to say that it doesn’t have to.
It is the free version of the software at the moment but if it proves popular then I shall upgrade it.
As it is a bit late tonight I shall probably not be there first thing tomorrow morning.
