WP Multisite question

[bns666]

I created an account for site1.com.

Now in site1.com/public_html i have folders site2.com, site3.com, site4.com and site5.com each working ok as separate sites.

I want to install WP Multisite so it will sit in site1.com/wp and that I can use it separately for site1.com and all other upto site5.com.

This is the first time I am working with WP-MS so help is appreciated since all I could find on codex refers to installing it as either with sub-domains or sub-folders and not each site on it's own domain.

If I use it with sub-folder option should it work for each domain?

get the domain mapping plugin, and setup your apache to point all the domains at that root directory.
