ok bit behind in doing coding for site sorry...
but as promised here is chat system for people to use www.russdev.com/edchat/
at moment not integrated into edugeek login system if i ever get time will try and do it but if someone wants to take that project on then they can..
also reason we stayed away from irc based chats as 99% of us would not be able to access it from work due to firewalls etc
there is a page on wiki for schedule chat ideas...
