Quite simply, it's a school blog. It used to be on the school LAN as a WordPerfect file but we moved to Blogger in 2007. Some more history can be found in Beginning Notes.
Taking a look at the original Providence Academy News is highly advisable, by the way.
P.S. WikiProv wasn't really a wiki. More like a collection of files. Reminds me of an FTP server. Oh yeah, and that's where the URL came from. Sorry about that...
