I am thinking about buying Invitex. However I need to know if this functionality is possible:

Can admin set a minimum invitation limit for users? Meaning that a user has to send out x-number of invitations or has to have a minimumm of x-succesfull invitations to be able to use the site.

Is this scenario possible? Also I woule like to know if there is a migration path from Parainvite to Invitex?
