I frequently post to tumblr via the tumblr bookmarklet. I also manage two different tumblr sites and once in awhile I would accidentally post content meant for one site onto the other (forgot that I was logged in with the wrong account).Does anyone know a way to customize the bookmarklet so that it will only post to a specific account? Or at least warn that the wrong account is currently active?
