Sometime Today, Sameer Shinde assembled some asciibets to say:
we can add each other in our messneges list where we can have instant online support from our friends n other lug members we can also do conferancing ( which we can say other way of online meeting )
Conferences are not the same as IRC. In IRC anyone can enter and leave as they please. In a conference, you have to be invited.
IRC is also an open protocol, so you can use any client of your choice. A conference is tied to the service you're using (MSN/Y!/AIM).
