If nothing is entered in the "About Me" section of your profile, only "Send Message" appears under the info section, as opposed to also displaying things such as occupation, birthday, etc. Filling in something in "About Me" fixes the issue, but this doesn't seem functionally correct / intended.
Let's not think that far ahead floris We need to look at it how the user would look at it lol
Since you have controll over who to add, that's no more than actually typing a person's name in the recipents box of a normal private message system like vB. I think this system combines the best of both worlds.
