How about supporting it? I guess that it's not hard to implement.

Do people actually use that service? I've never heard of it till just now.

If enough people use it, I could implement it. But if only a few people use it, might not be worth the time. :)

Both stackoverflow.com (programming question site, quite big) and kongregate.com (flash gaming site, quite big) use it. Using it, you can display avatars based on a user's email address. That means the user doesn't even have to do anything.

base on email? how they do that?

You upload your picture to their site, and I add code on BTG to fetch your image based on the email address you entered. The email address you entered here would have to match the email at Gravatar.

Would there be a way to turn it off? I only signed up to Gravatar for a picture on that site for FF add-ons on user-scripts.org, and barely use it. And I don't necessarily want the same avatar for multiple sites. Seems like a good feature, options make everything great =]

Your avatar uploading system currently is wonderful, showing the 3 different types of views that may possibly show up around the site.

Thanks. It did take a bit of work to create my own avatar system. I probably won't use Gravatar just cause there are few that use it, and like MidgetMan said, the avatar uploader I made works pretty good :)
