People please stop deleting accounts you no longer want, particularly if the name of the account is great and could be used by someone else! Lets save them!
Stick your unwanted account on http://blogswapper.wordpress.com and connect with someone that would like it and transfer it!
Alternatively, if you find an account that isn't being used... drop them a message saying to offer it up to http://blogswapper.wordpress.com and find a new owner for it.
It sucks that good names die... lets try and save a few! :)
