^^ your underpants are smoking as I do remember you baiting Business Time about how many posts you had and how he'd never catch you!!
Ok back on topic. If you change your ingame name from xxx to yyy all you need to do is put a ticket in AFTER the name change has gone through and if NO ONE else has registered the new name on the externals (I would suggest you keep quiet here until all done as am sure some would find it hilarious to pinch your new nickname and taunt you!!) then we will (at no extra charge) change your external name for you. Um I say we but it won't be me as they don't let me near the important stuff!!
Now your rep and post count would be the same but not sure how the search function would cope with having some posts under xxx etc etc so change your name and let us know!
So check before you change your ingame name that no one has your proposed new name on our member list which you will find
here, then ingame go to settings then change username and fill in the details. Keep quiet till name is done then pop a ticket in on these forums and request your external name be changed.
Then tell your friends that you are now (insert scary name here)
and all for 500 premium points how we do it is beyond me I tell you :icon_wink:
