I just discovered the group so I thought I'd pass along their details. The group is a loose affiliation of local grassroots groups that organize town hall meetings, marches, vigils etc. If you want to get involved, this seems pretty painless. I talked with a local organizer in my Texas community and at least here, they're not even looking for donations--just people to march and stand up, attend town halls, etc.

Sadly though, this isn't one of those fancy paid shill gigs.
