Hello,
I would like to suggest 'Nearby Groups' as a method for sorting groups in EasySocial by location/distance. This could work the same way as Nearby Events -
http://easysocial.stackideas.com/events/nearby.
The majority of groups for our purpose are physical locations and it would be really useful for the user to be able to view/sort groups that are nearby to their location and relevant to them. Additionally it would be wonderful if you could provide an option through google maps for directions to the group location.
