Donna,
Scrappy and I have been talking, about another chatroom we use, and we both love. We haven't had any problems withit at all, (so far). And thought it would be awesome to add here. It is called Flashchat. It does cost, but only $5.00. (I will chip on the cost, if you decide you like it!) It is compatable with our forums. We don't want to add any work to you, and if it is too much trouble to fool with it, thats OK, we just loved it and thought you would too! It has skins you can use, you can PM someone in the Chat, create private rooms, and more.
OK, I will shut up about it now.
Here is the link to the page with info on it, in case you want to check it out!!
