We're humbled to hear about that. Moqups will always be free (including the premium features) for non profits/educational organizations. Please drop us a line at contact[@]moqups.com when you get the chance.

Do user groups count as a non profit or would that need to be more formal (as in a 501(c))?

With all the honesty, we haven't decided yet.

Moqups will continue to be free in its simplest form, so feel free to enjoy it. After launching the premium features, we'll provide an application form and carefully analyze each application in order to determine if it's eligible for free use or not. Also, we'll make sure to provide more details about what is needed for qualifying in this program.
