Question   What does it mean when editing a membership if visible is set to yes or no?

A. If admin access is set to yes, then members belonging to that membership are able to access all pages that an admin can access.

A. Because you are selling multiple memberships you would need the $600 Tool Truck.

A. When editing the membership, in the URL at top you can see the id for the membership.  Then, use that id for the membership and add it to the url as shown below replacing the id number with ID:
/join/USERNAME?membership=ID

So, for example if it is for username john and membership id 3 it would look like:
/join/john?membership=3

Or if putting it inside the WYSIWYG of a capture page you would put the following code for membership id 3
/join/~username~?membership=3

A. The easiest way, if possible, is in the database to temporarily make any suspended members active.  Then make all the members in the membership suspended.  Then from members delete to delete all suspended members.  Then suspend the members that were previously suspended.

A. Yes
