If you're particularly engaged on the net neutrality issue -- or if you're not at all, but interested in new models for online deliberation -- the National Science Foundation-funded Deliberative E-Rulemaking Project (DeER) at the University at Albany (SUNY) and Texas Tech is "test[ing] a new model for citizen input on proposed rules and regulations by federal agencies. We are recruiting people to participate in an online message board discussion on a possible FCC network neutrality regulation."

The project is supposed to begin in late August, but you can sign up for it right now. More here.
