This site now makes use of gravatars!
If you already have a gravatar, then all you have to do is register with the email that you signed up to the Gravatar service with and as you know your gravatar will show on any comment/post you make.
If you don’t have a gravatar do not despair! Go to here and sign up with the email that you signed up to Southanuk with.
Its a nice little feature, but its cool.
