about pidgin

[M Mn]

Excuse me for being an ignoramus but what good is this program? What should I use as a server and why doesnt your software at least point you to a list of servers?
Or be a little more helpful with directions...you know, like a simple way to do this? Yes I have GTK+ installed as well

Is there truly any way to text free over the internet? With one simple app without having to download a bunch of extra stuff that needs configuring too?
