oops, rookie mistake!
Thank you so much for the welcome, all! I have seen many questions answered on bikeforums.net that I myself had, so I'm glad there's such a great community of cyclists out there that are so knowledgeable.
Juha, you're right - I didn't know that there was such a beast, but I understand now. I will post my question again in that forum. Thanks!
Fallrun, I'll be happy to write in your blog just as soon as I actually start commuting! I'm glad you're successfully ditching your car, and good luck. I'm glad to know I'm not alone in my crazy quest.
