Can anyone tell me how to delete an old X-box Live account o

[Spongebob]

Its a pain having the old Tag show up and budge in the way of my new Tag. I want to wipe it off the system but I see no option to delete it.

Sorry if this is a little late, but you should be able to remove that other Gamertag by going to the X-Box dashboard --> memory, and deleting the save for "X-Box Live Accounts". It will remove all of the Gamertags, but then you go back to X-Box Live and and go through the account recovery for the one you want.
