Fixes to the Main Menu

I finally got around to fixing a few of the problem links on the main menu. Took off the Old Site and Forum links, since they hadn't been working since the hack-attack, and were even less likely to get fixed now that I've moved to a new site and have no intention of reinstalling the content management system that the hack attack broke. So, the Old Site is dead, long live the new site! (I may try to get a forum system up and running again, but for now Blogger's comment system seems good enough...)

And, in related news, the Christianity link in the main menu is now working again, now pointing to an annotated index post that will eventually list and link to all the Christianity-related posts on this site.
