I just came across the Citizens Briefing Book at change.gov. I have no idea how effective this will be in helping the new administration to stay in touch with the grass roots, but I like the idea.
There are thousands of ideas listed there, many of which are redundant. One of them so far was originated by me, and it is a topic you are familiar with from these pages. You can find it here.
I strongly suggest that you sign up with this government web site and vote on the ideas that you feel strongly about. I have just begun to browse through the ideas there, and it's a bit overwhelming if you try to absorb it all. I started by searching for a few topics. By far, the issue of the drug war and decriminalization of marijuana is the most active topic I have come across so far. Also very active is the issue of investigating the outgoing administration for war crimes.
Check it out.
