Hi
It would be a great idea and feature as site owner to interact with users more often and offer them some promotion or share event etc. I suggest to have emailing template system to be able to create and save based on event such as valentines day, eastern , Christmas etc with site logo and footer. so these email then can be saved and used to be sent automatically within Calendar to some or all users like paid , free, active, inactive, men, women etc.
I hope everyone else agrees.
Thanks
