Topic: Multiple Site Manager...

I'm trying to add a site for the first time and having a good bit of trouble. I've tried to use the EE docs, but it assumes that I know what 'm doing, and evidently I don't. Does anyone know a good tutorial or screencast for this topic.

I guess one question I need answered is do I have to keep all the sites inside 1 folder. I'm hosting the 2 sites on the same account in subfdolers with add on domains. For example:

my current site (single install) is http://faithworld.com and the files are located at "http://jbirdmedia.org/faithworld

The new site I want to add on is located at http://jbirdmedia.org/clintbrown

Is that possible or does the new sites folder have to be in the "Faithoworld" folder?

Thanks,
Jason
