+<%~--
+
+This page is included almost everywhere in the templates to display a username.
+Things like linking, group highlighting, buddy highlighting, etc. are handled
+here, in one central place, instead of being duplicated all over the place.
+The general usage is, instead of something like:
+
+... <a href="<%GForum::SEO::url(type => 'profile', id => $user_username)%>"><%user_username%></a> ...
+
+you do:
+
+... <%include include_username.html%> ...
+
+This will take care of special classes for buddies, administrators, disabled
+users, groups, moderators, etc., as well as
+
+In many cases it is necessary to display something other than user_username --
+for example, for posts and messages -- in which case you can set the
+include_username_display variable to the username to display (it will be
+cleared after being used).  This also handles the case where
+include_username_display is set, but user_id isn't set, as an indication of a
+deleted user, in which case you get a <span class="username deleted-user">...
+
+Also note that this include will produce *no* whitespace around the <span> or
+<a> tag returned, so whatever whitespace padding you put or don't put around
+the include will be the only whitespace present.
+
+Some notable exceptions to the ability to use this include exist where only a
+username is stored -- the last poster data for forums and threads is a good
+example of this.
