KoolIM – An online Web Messenger.
KoolIM is an online web based Instant Messenging service. It is really coool, elegant and make nice use of Ajax. KoolIM does chat through a browser popup window(which is annoying for some users). So within a single browser window you can use the following instant messaging services AIM, MSN, Yahoo, GTalk, ICQ. There is no need for any registration, but for quicker login into all the IM services you can create a free account.
Some of the competitors for KoolIM include Meebo(which i personally love most), ILoveIM, Mabber, eMessenger, MessengerFX, Wablet, Goowy, Imunitive, RadiusIM. The web based online chat offering is constantly growing and is getting crowded day by day.
These Web based services are getting really popular in colleges, schools, and in work places where IM clients are blocked.
