California gubanatorial candidate Gavin Newsom will be conducting a live webchat at noon Pacific on Wednesday, October 28 (link).

The webchat is about "green" issues (including Newsom's push for "mandatory composting"), but that doesn't mean you can't submit questions about this in order to send Newsom a message.

Apparently the questions he'll be asked will be pre-approved, but you can also submit questions as comments at the link above. If they get enough questions about that, it will definitely send a message.
