If you are writing comments very often and want to give them a ‘better-to-recognise’ personal note you should have a closer look at gravatars. Via this service you can specify an avatar for your e-mail address. Our journal fully supports gravatars and you might use it on other pages as well.
Just create an account, verify your e-mail address, upload an avatar and you are done. It’s all free.
Don’t take this wrong, its not a must. I just want to inform you about the technical possibility.
