About to fall asleep, but note to self for later: $user->get_avatar_url() / get_avatar_html(), with a site-wide option for which avatar host to use

Great, for that function please remember create a panel in settings to set $size, $rating (really important this one, no all imageboards allow p0rn images), $default (possible $data_href/themes/$theme_name/images/gravatar.jpg) maybe the admin only can set the file in that directory ($data_href/themes/$theme_name/images/).

http://www.gravatar.com/avatar/$hash?d=$default&s=$size&r=$rating

commit:e18c8d2 adds the function for use by themes, still needs configurability and someone to use it

82bf804 adds (fixes) the user page

159a862 adds configurability; default is gravatar with no special options, options are left to the advanced menu and take the form "d=$default&s=$size&r=$rating"

Can you add the class gravatar to it?

id="gravatar" or class="gravatar" 

dd65b63 adds the classes "avatar" (which will be used for all avatar hosts) and "gravatar" (if for some reason you only want to style those particular ones)
