Just as a little information the display of "who is chatting" in the chat room in the whats on section can be re-worked to display on the forumhome - top right / left etc.
The reason i have done this was the simple fact it seemed the members (lazy as ever) will not scroll or look at full sites pages, which with location of the whats on being low down as default.
I reworked it to the way it is done in the attached picture and with the flashing icon - and yes people are using the Chat area more frequently and have commented on the fact they can see it more easily. This is just to let people know it can be done.
it can be seen here providing the chatroom is being used........
