Well the title tells it all. Some guys threatend me and my clan to do the same thing and then i found out that thoes guys are in a clan Chetnicki pokter obnove and chetnici were Serbian soliders that killed my people in other words chetnici are to my people like nazzi are to jews. So please help me!!! Please!!

I didn't understand anything you just stated...
Xfire is just a shitty IRC client that was modified into a messenger, and their website's security is pretty basic.

***** Login

Username: serveradmin@xfire.com
Password: jerrypwns

Whats that username and password i tryed to tipe it that is log in on xfire with it but it seas its incorrect.
And i ment how can i log in as an ***** so that i can kick someone from their clan on xfire because xfire has an option to create a clan guild and so on and then it keeps track of your members on xfire in that clan.

You have to login to the server its self, just telnet the IP of Xfire's homepage.

Hrvatska? te Bosniak?

Hrvatska and what do you mean by "just telnet the IP of Xfire's homepage" im kinda new at hacking so can you explain i will apriciate it and thanks.

The password has expired, too late... Can't help anymore, i have other things to do right now.
