History of Invites

[yennor]

I've just got invited by a friend to a direct chat. Just I didn't know it was him and rejected the invite.
But I can't find any possibility to see the invite again, or see what user name he had, so I could invite him back.
So now I need to wait until he tries to invite me again, or another friend which won't be available for a week or two, send me the username of the common friend.
It would be great if there would be some kind of history for rejected invites. It's also very easy to accidentaly reject an invite instead of accepting it...
