First of all, this product is fantastic.
Thinking about Customer Accounts in Social Mobi Survey.
It will be fantastic, if customer accounts could expire, (Developer and Reseller License) the expiration date should be configured (manually maybe) by site's owner (I mean, for us, by us).
This feature, if you decide included, will be very helpful.
In the members sections, you can manually revoke access in a matter of minutes. This function is available if you click on "Manage Clients"
But we will consider the option of adding an automated system in our future updates.
If there are any queries, please raise a ticket with our support desk and we will be glad to address it.
