User testing

I have been testing a structure that allows to graphically manipulate content among different users.

Basically allows people to visualize a group of 5 hot contacts (the ones they call more often), they social groups and the media content of themselves and the other users that run the same system.

The user set ups privilege levels in order to allow different people to access more or restricted media.

There is also a timeline in the top of the interface that displays the proximity of the user´s appointments.

The reaction have been positive. with some details to fix, like the position of the clock and the sequence of actions, like is it possible to writte a message first? or do you need to choose the recipients first?
