How do I get a twitter username that's taken but has rarely been used? Expiration?

[aleksandr]

My real name is taken on twitter, but the account hasn't been used since November 18, 2008 and only two tweets have ever been sent out from it. Is there a way for me to obtain this name, since the account is most certainly not going to be used ever again? If not, will the account ever expire?

well you might not get the same username but if you add any number like 1 or any extra latter at the end of your username it will do ! like if your desired username is @RyanAngus then you can try adding numbers like @Ryan Angus1 ..
