I use ichat regularly to do video chats with friends. I am having a problem customizing the alerts to sounds i prefer. It will not let me add new sounds to ichat even though it says i can. Also, is there a way to alter the appearance like add new skins or themes? I'd almost like the buddy list to blend into the backround sort of like the transparent quicktime controls...
If none of these are possible, are there any alternatives to ichat that will work just as well?
