Hopefully a basic question, but one that plagues me nonetheless.
I have a couple of self-hosted WordPress installs on my website. An issue that I have is that I have common users registered for each site....however some of them feel its a pain to have to go through the signup process each time, and have to juggle multiple accounts in order to comment.
Is it possible to commonize accounts, for instance simply using a WP.com/org account and accessing my blogs in that manner?
