XF 1.1 Usergroup specific content in post permalink


Well-known member
I'm trying without success to add some text between the post author permalink and the time stamp, but only if the post author is a member of usergroup X.

It's the part under a post (in the post template):

I'm editing the template to add the conditional as follows, this bit shown is the author then my bit:

<xen:username user="$post" class="author" />, <xen:if is="{xen:helper ismemberof, $user, 6}">Message for post authors in group 6</xen:if>
Nothing shows for post authors in usergroup 6. I am assuming then $user is not available to use in this template? That being the case, is there any other way to add a usergroup 6 specific message only to this part of posts made by members in that usergroup?
