From The Entourage Help Page

Changing the Main Page to Welcome

Edited http://entourage.mvps.org/MediaWiki:Mainpage to use http://entourage.mvps.org/Welcome instead of http://entourage.mvps.org/Main_page. This also changes the Navigation sidebar to use Welcome.

If the time ever comes to completely migrate The Entourage Help Page to a full wiki then /usr/www/users/dsmross/.htaccess can be further modified to uncomment this line:

# RewriteRule ^/*$ /ehp/index.php?title=Welcome [L,QSA]

which will allow all visitors accessing http://entourage.mvps.org to be directed to http://entourage.mvps.org/Welcome.
