 It would be nice if ikiwiki, particularly [[plugins/comments]]

+(but also, ideally, recentchanges) supported user avatar icons.
 
 Idea is to add a directive that displays a small avatar image for a user.
-Pass it the email address, openid, or wiki username of the user.
+Pass it a user's the email address, openid, username, or the md5 hash

 	\[[!avatar user@example.com]]
 	\[[!avatar http://joey.kitenet.net/]]
 	\[[!avatar user]]

 These directives can then be hand-inserted onto pages, or more likely,

+For openid, openavatar sucked and is now dead. So we need to use an email

+Hmm. Suppose the gravatar hash could be calculated from the email address

+Or, for openid, could use <http://paulisageek.com/openidavatar>. Which
