I think you can post on it. Just click on the little icon at the bottom left of the day and put up your info. Alot easier to use than the one on Ebay. Now I just need to get all the dates transfered. Oh and we can put up notices like when ATC's are due and the competition end etc. too.
I also found that if you click on the title on the calendar page you can leave messages there. So like when it is a Birthday then click on the name and then you can leave your birthday wishes there!!! How cool is that.
