In our communities,

[G_j]

Of course, most of us will be working locally. If you are on Facebook, you might check to see if there is a local Bernie Sanders Facebook page, and if not, set one up. It's a good way to connect with other supporters locally. We will need to be reaching out to organize with others in our own communities.
All ideas welcome..

1. I've already hooked up with a Bernie's supporters group and there's another supporter in my area.

I'll pm you the link to the group.

2. Also check your county democratic central committee.

It will be a great place to find others to begin forming local groups.
