I personally understand the need for requiring invitation. However I myself would prefer if it wasn't. I actually accepted the invitation, thanks btw, then saw a few people had actually been to my user name page. Why? no clue but I suddenly didn't like the idea of a rainbow flag on my user profile. I don't hide who I am from people, but I don't shout it at everyone either. I guess just a lot of time in the military and various other non-friendly areas. Almost all of my friends know, anyone else if they ask I wouldn't mind telling them. I just don't like the idea of being pre-judged. Yeah meet me, talk to me, like me or hate me, then find out. Not the other way around. Again just my opinion/vote.
