I just upgraded MacMegasite to Drupal 4.6. The upgrade was very easy, since it doesn’t use the event module.
This site looks great. By comparison, MacMegasite looks like something thrown together using PHP Nuke. I'm sure you can make it as attractive as McDevZone. (BTW, I'm working toward using Druapl at Low End Mac. One step at a time. Still learning enough CSS and XHTML so I'll have a better understanding of what's going on behind the scenes.)

The site was originally made with PHP Nuke, so when I switched to Drupal I attempted to keep the same appearance. I'm planning to switch to a nicer theme.
