-included in eg, a comment post via a template. Possibly included in a
-recentchanges page item via that template too?

-The avatars are provided by various sites. For email addresses, it uses a
-[gravatar](http://gravatar.com/). For a wiki username, the
-user's email address is looked up and the gravatar for that user is
-displayed. (Of course, the user has to have filled in their email address
-on their Preferences page for that to work.)
-
-For openid, openavatar sucked and is now dead. So we need to use an email
-address instead, I guess. Problem is that the email address of a given
-openid is only known when that user is logged in and making a change.
-And we don't want to leak an openid user's email into a page either.
-Hmm. Suppose the gravatar hash could be calculated from the email address
-and embedded instead of the openid?
-
-Or, for openid, could use <http://paulisageek.com/openidavatar>.
