There were some Deansters hawking signatures at an event I attended this weekend and I realized that I couldn't sign - I wasn't registered to vote. I needed to remedy this and thought I'd share. The ChicagoElections.com website is official but kinda sketchy - it redirects you to a poorly designed site. But it does include a form to complete online and mail in for your registration. The lovely League of Women Voters have a list of chapters in Illinois where you might find other sites, especially if you aren't in Chicago.
