We do not take trainer requests in the forum, trainers are made or updated based on their current overall popularity amongst the entire WeMod community. Here’s how it works: Game Queue.
You can see the currently scheduled queue for trainers that are in line to be developed or updated by clicking the Creators tab on the WeMod app.
Make sure to show your interest in any trainers that are not developed yet by clicking the Notify Me button on the trainer’s page within the WeMod software.
