You are the review board
Review
Nobody at the studio approves or vetoes ideas by hand. If the studio declined an idea, three of you can send it back. If a finished asset is wrong, flag it from its page, and three of you can ask for a rebuild. Ideas declined for their content stay declined.
Declined ideas · vote to send them back
The studio declines an idea when it cannot tell what single object to build, or when a build failed three times. Your votes overrule the first; the second gets a fresh start.
Flagged assets · vote to rebuild
Flag a problem from any asset's page. Once an asset has flags, three rebuild votes open a rebuild request that takes its turn in the queue like any other idea.
