roaringfortefan
Well I think you might have compassion grounds to appeal against Jairducochetfan because its such a crap user name, but roaringfortefan is nearly as bad and could be confused with a hotel chain anyway. I think you'll need to find something a bit better than that.
I tried mucking about with the settings I have and ended up banning you, so perhaps it's best left to those who understand these things. I can change your avatar and signature, and I can change your name in your profile, I can't see that I can save your new name though, so it probably wouldn't go through.
I do have sympathy with yourself though for being saddled with such a shite user name. I mean it just isn't catchy, can't be abbreviated, and lacks charisma. So I think there might be grounds for granting you a dispensation, but you'd need to plead with Gareth
