Welcome to the community! 
Trainers are made if there is enough interest from the WeMod community in those games.
- WeMod automatically detects how many members have the game on their PCs.
- Follow the game by clicking “Notify Me” on the game’s page in the WeMod desktop app. This also helps the trainer developers see how popular the game is. And it keeps those interested notified if it enters development.
- Pro users can boost games even further up the queue using the Pro-only boosting feature, if they wish to.
