Im 90% sure this problem has been addressed before, but i think a good suggestion to AG is to add the ability to privately comment on someone's profile. Being mostly on the forum game side, i love the game mafia, but i cant host or play it without private comments.
That is not the only reason why these would be useful. Some people like to write comments or receive them that are only between them and the other user. im wondering if this could happen, and if so, when.
