Renaming/rename token

I haven't written here in a long time but all "the cool kids" seem to be over here now rather than on LJ so I guess I'll hang out over here too as I already have an account.
However, I do want to change my username and apparently that requires a rename token which I do not have and given the exchange rate among other things, I am not interested in purchasing.
Does anybody have such a thing?
Thank you!!!
