Just got this email:
Hey Happy DreamHost Content-Managing Customers!
Just in case you don't get the newsletter, or don't like it,
we're also announcing the fact that there's a new one-click
install here:
https://panel.dreamhost.com/?tree=goodies.installer
It's "Mambo" (see http://www.mamboserver.com/), the hugely
popular open source CMS software.
Yippee!
The Happy DreamHost One-Click Announcement Team
I’ve heard good things about Mambo from a friend of mine who uses it to manage a gaming clan site, but I’ve never played with it myself.
