Regi Login Id -____-

As i am currently bored of Combat Arms i heard that CrossFire has lots of pub hacks that are really good.. So i've decided to try it... So i go on the website and then click "Register" so then comes up the forum to fill out.. It says

Login Id:

So i just put what i usaully put- Azzazor - This Id is being used please choose another...
So i carry on putting usernames i use but all of them are taken... Me being insanely annoyed then start putting like au9sdgh for the user ID but that is taken as well so ive been trying like EVERYTHING but all the ids are taken... even things like 43ga4thu etc.... Any ideas?

Shiiiiit i didnt realise some other guy had posted the same thing aswell -____- Does anyone have an account i could have that they are not using? Pm the id/ p/w security question+answer etc
Thanks
