At least until I found Doodle. Doodle is an online tool that lets group members indicate when they are free to meet.  The organizer creates a poll with the times they have free – which makes it good to be the organizer!  Once the poll is created, the organizer sends a link to members of the group via email.  Members then click the link and indicate on the poll when they can meeting. Once everyone has voted, the poll is closed and the best time (or that there is no good time) is apparent. Easy peasy!  And free.
