Organising filming times with actors

Below is a screen shot of a post which I put on Facebook arranging when we will do more filming for our music video. Facebook is the most efficient way to contact our actors as I can easily tag them all in a status and they all check their accounts on a daily basis. They can all talk communicate with each other as well as me as they can comment on the post and therefore they can ask me and Kaylee questions and tell us if they are unavailable on any of the days or times.
