UPDATE 3/6: Fixed the missing reply buttons problem.

Changes the main article font to Verdana; cleans up the front page a wee bit; removes the (IMO) useless submenu, footer, and the 'PHOTOS' & 'WIKI' links from the main menu; changes the horrid ALL CAPS nonsense from the dropdown menu to a more readable Capitalized Case; changes the font sizing and line-heights a bit; makes links in blog posts stand out more and the text in comments a little easier to read.

Customization:
The footer menu can be brought back with new styling, simply comment out

#footer .main_navigation {
display:none !important;
}

and remove the /* */ from around the code below it.

I included long font stacks in various places, try switching around the order of the fonts or adding new ones. Suggestions: Corbel instead of Verdana; "Segoe UI" or Candara instead of Trebuchet; Frutiger, Univers, or Calibri instead of Gill Sans or Helvetica. Experiment with it and see what looks best to you.
