They have Wordpress built in, you might not need to set up any database stuff manually.
They also have support for MediaWiki if you want it.
The built-in Wordpress comes with ads, and new plugins and themes need
to be installed by the Sourceforge staff, so I installed Wordpress at
http://bitcoin.sourceforge.net/. The admin page is at …/wp-admin/,
with admin/Wubreches3eS as login. If there’s something to add or
change, feel free to.
The current layout is just a quickly applied free theme, but I’ll see
if I can do something more visual myself.
The MediaWiki might be quite useful for maintaining the FAQ, which
could be retrieved from there to the main site somehow. The wiki says
I need to be an editor or admin to create a new page, which is funny,
because
https://apps.sourceforge.net/mediawiki/bitcoin/index.php?title=Special:ListGroupRights says that users can create
pages.
