Tumblr Url Help Please?

[Taylor]

Unfortunately if a tumblr URL is taken despite no activity the URL can't be used again unless the owner deactivates it. The URL might be saved for further use by another user or just an account someone gave up on. This has been a major complaint throughout tumblr because some of the best URLs are no longer used and people want to free up some URL so you aren't stuck with some stupid random name. Hopefully they'll fix this sometime, though people are hacked and there have been issue with some blogs being randomly deleted I doubt you'll be able to use the URL.
