Sometimes I really miss function to send an private message to some users I meet for the first time in an event etc ... Afterwards I can see their user and activities. But to align an common training or exchange maybe the phone numbers - only comments are available. Because these information can be read by a hugh amount of people, thats not the way I want to share my personal data. So via private message this would be perfect ... or maybe add to the profile these data and I can ask for allowance to see these data or offer my data to a specific user?
