As part of President elect Barack Obama’s transition, a new website has been created at www.change.gov.
When it comes to taxes, Obama’s agenda can be found here. Feedback on the plan/agenda can be submitted to the administration via the web.
My personal disclaimer: I’ve been on the web site but I haven’t clicked through beyond the tax agenda. I also haven’t submitted any feedback, so I can’t speak to whether you receive a reply, etc. I’d love to hear your experiences on the site.
