salam,
Thanks for those links. The problem I think with an external chat tool using Yahoo/Paltalk is that not everyone who posts here is from the US. Therefore, when its late evening here (which is when I can chat), its early morning in other parts of the world and therefore it becomes hard to keep yahoo/paltalk on all the time, especially at work since I don't use these there.
Anyway, I'll try those links and see how it goes.
