hi guys, i have just created a new members only site using modx - in my own special hack way

. I have an existing public site displaying the members information (manually set) . I would like to gather the members info maybe using eForm and dropping that into the public site (this site has not been setup using modx).
the eform will need to gather this type of info...
centre name
centre location
suburb
phone
email
contact person
website
once done how do i link it up to the public site?
thanks
