This user (http://xenforo.com/community/members/eqnoble.1321/) has blocked his profile from viewing by others. What XF tells us is: 'This member limits who may view their full profile'. Yes, thank you, but what can we do to see it then?
The enduser of XF only sees this message and being new to XF as a brand new (and soon to be marketleader) platform, people don't know how to be able to get access to this profile.
What XF 'should' do IMHO is presenting the enduser with additional guidance saying something like: 'Become a member (link to registration page) of ThisForumName to get access to this users (or ThisUsersName) profile'. Or... 'Follow (link to follow function) ThisUsersName to get access to their profile'. Edit... Or... 'ThisUsersName is not following you and therefor you have no access to their profile'.
Something like that is needed, because the message now is too bland and not inviting in any way to generate interest/social activity.
Brilliant, another great suggestion, isn't it?
