For sophisticated Internet people:

We use gravatars on our site.

For all others:

Your image that shows up on our site is called an avatar, an image that represents yourself online. But we also use something called a gravatar. A gravatar is just like an avatar but it is a "Globally Recognized Avatar." It simply links to your email address so whenever you enter that email address as criteria for participating in a website, like posting a comment on the Ask Adam League, this gravatar will be your avatar. It just follows you around to whatever website you use your email address with.

So, if you want to use an avatar on the Ask Adam League make sure you are logged in and go to your profile page. You can find this on our sidebar as "Edit Profile". Click on "Select Your Avatar" and you can upload any image you want. Whatever you select here will only work for the Ask Adam League specifically.

If you want to use a gravatar then go here. This is the logo you want to look for:

The instructions are simple. Create an account and assign an image to the email address that you want to use. Provided that all of your earlier comments were used with your 'gravatared' email address when you assimilated to The League, then all of your postings will be retroactively updated and all new comments will have your new gravatar.
