The process is easy. Just go to Gravatar and register for an account with the same e-mail address you used for this site, and you’re good to go. Add a picture to your account there, and it should show up here and any other site that uses Gravatar. It’s seriously the easiest sign up process ever in the history of dude-kind.
It’d be nice to see some shiny new avatars for all of those comments on Season 2, Episode 4 of TLW, which will be here within the next couple of days.
Go forth and register, and be ye anonymous no more.
