[PGCanada] Logging In to the Wiki

I've added basic user authentication to the PG Canada wiki (http://www.jenzed.com/pgcawiki/pmwiki.php). You must now log in before you can edit a post or add a page. I've created login accounts for everyone that's been active on the mailing list in the last few months. Use your first name (in lower case) for both user name and password, then click the "Change Password" link the in top right corner to set a new one. For now, please post problems or account requests to this list. jen.
