A regular user can whisper suggestions in the ear of a gold/platinum moderator. Maybe that moderator will be inspired to do some research.
We usually discuss nominees as a team before extending offers to join a trial, so impressing only one moderator might not get a suggested user into the final list of nominees.
If you run my code it also explains how mods are selected
Qualified SoloLearners will be contacted by a Platinum Moderator with an invitation to be part of a Moderation Team. You may also be contacted directly by our staff.
