Question   What is a piggyack domain (explain)?

A. You are able to define a tracking campaign; the tracking information is included in the notification email that is sent and also stored in the members Area.

There is a section in the members area where you and your members can create url's to track different tracking campaigns when using a capture page. 

Also, you can specify the tracking yourself by adding a hidden field to the form with the name "tracking" and for the value the title of the tracking campaign.

Also, you can append tracking details on the end of a URL of a page. For example if your URL looks like this:
domain.com/page1.php?user=myusername
To add a tracking campaign titled facebook you will add it to the end like this:
domain.com/page1.php?user=myusername&tracking=facebook

A. If you transfer your domain name then you will no longer have the old domain name,
and people will login at the new domain name to access their members area.

If you do a piggyback domain then you keep the old domain,
and people would login at the old domain, not the new piggyback domain.

A. Yes, you can add additional domains to your software that replicate out pages for each Member.  Our term for this is "PiggyBack Domains".

A. Resource pages are only seen in the members area.  The only way to create new pages on a piggyback yourself is to duplicate the page installed on the piggyback domain (using the duplicate button while editing the page)
