This sounds very bossy but I honed the rules so that , if played properly, the game works.
You should wait until the clue is declared open by the setter if you are 'out'.
If the setter does not declare the clue open after 15 mins they should be prompted.
It says 15 min time limit but the setter may declare the clue open early.
I hope this clears up any ambiguity and you don't mind my interfering.
