Paul Gilbert also notes in interviews that a fan submitted the idea for the name:

In 2011, they held a contest to have fans submit artwork to be picked to be on the album's front cover.

He was also the first "fan's choice" inductee, as fans around the world submitted nominees for the spot.

The band also invited fans to submit close-up shots of their faces in order to make 2,000 different individual covers for the album.

Coldplay launched a contest through their website, in which fans submitted self-made music videos.

During the first phase, fans submitted suggestions.

Readers and fans of the series can submit ideas and designs for monsters that appear in the manga.

The band then suggested fans create and submit album art to become the official cover for the unreleased album.

In each special Marc Cherry and an actress/actor of the series would answer questions that fans submitted to abc.go.com.
