We use Meetup.com for our calendars. The technology of Meetup.com is very user friendly and they have done a fabulous job of programming in a very useful way, and the price is reasonable. Please note that most of the people involved with Abhyasa Ashram and the Center for Nondualism do not click on Meetup.com links to show that they are coming; they just come. The effect of this is that it often looks like nobody is coming to meetings that are well attended, remembering that this is a small ashram, and a typical turnout may range from 2-3 up to about 10-15, depending on the event.
