Not a single mention about what it is you want feedback on then how do you expect a meaningful feedback, maybe if members have a clue on what you are working on then they can give their opinions base on what they understand, or that's what the calendar is for! Probably am not getting it right.
that calendar is for the people that want to schedule a meeting with here.
But before that it will be good for the OP to explain what is the topic that you will discuss later
