What are applications like IdeaBox called?

Question

I'm trying to figure out the generic name for systems that allows users to contribute with the development of new features. Kickass Torrents has a very interesting app in it's site named IdeaBox and it's divided in stages such as: suggestions, planned, in progress, completed. It has a voting feature for everyone with more than 100 reputation and that's pretty much all. I wanna look at opensource alternatives but that's not possible if I don't know how it's generically named.

Answer 1

I haven't seen any especially unique name for these, just them referred to as suggestion boxes.

All Our Ideas operates as a service, but the software is open and available on Github.
BBYIDX is a similar offering that oddly enough had its start at Best Buy.
If you want to get more hands-on, the WordPress Ideas(and Kvetch) areas are almost certainly built on WordPress, via some combination of user submission form, voting plugin and the built-in registration system.
