The wiki serves as DreamHost’s web hosting manual, but also contains a lot of non DreamHost-specific information too.

The community supported wiki contains tons of information about working with Dreamhost from basic FAQs to detailed tutorials. If you have a question about your hosting, you can probably find the answer in the wiki.

Popular sections in the wiki:

Troubleshooting - if you are experiencing difficulties or errors, this should be your first stop.

Email Help - Covers all aspects of the Dreamhost email system. Having trouble setting your mail client to use your DreamHost e-mail service? Check out Email configuration.

Dreambooks - Info on setting up the popular free guestbook service.

How about setting up custom error pages, or using Crontabs ?

Another gem I found while browsing the wiki was this page about optimizing websites for better performance. Which is a good read for non-Dreamhost customers as well.

I could go on and on about all the goodies you can find in the Dreamhost wiki, but I will leave you now to go and check it out for yourself. I’m sure you’ll find something useful there.
