More Blog Improvements

A few changes here:

• Put schedule information into the sidebar. That makes it a lot easier to get an "at a glance" look at what we are up to.
• Added a static link to the visas entry.
• Fixed some dates and info that was incorrect in some of the South American destinations.
• Moved 'Contributors' down to the bottom.
• Comments are now mailed to a Y! Groups addr that will be read by both of us.

I tried using the "post by email" feature of this thing, but I couldn't seem to make it work. Will play a bit more later. Also, I'd like it if there was a mailing list associated with the blog that got mailed with each new entry. I will see about that as well.
