I have requested a plugin for the admin to make surveys of the type:
Do you like the web?
How many times a month do you connect?
Do you recommend it to your friends?
What other similar websites do you use?
etc
in a form, and then the admin can see the results, statistics by user roles and a lot of statistical dreams more, by asking me ask for graphics, forward invitations to complete it to those who have not, notifications to those who do they have completed it ...
Even simplifying tasks, I think it would be a plugin that was going to sell very little, it is quite complex and there are also many free websites to do user satisfaction surveys this type.
Please, think
Would you buy it?
