Sub-domain name change

[Archer_jl]

well, the old clan qld and I wish to change it to ep as back then, I was Co and time was stretched when I was designing the site back then. Since the death of Qld, I have been herding up everyone for the clan I've started up.
Neways, can the sub-domain be changed from qld to ep? The site has been updated so it needs to be moved too. Sorry for any probs in advanced.
