Would it be possible to create an official thread where people can ask for help testing specific mechanics on the cartridge? For example, I'm fixing the interaction between Sparkling Aria and Shield Dust, but I'm not sure about one mechanic. This task requires two systems, so not many people will likely be able to do it alone if I just ask in the mechanics research thread.
In this new thread, I could simply post something like: "I need help testing the interaction between Sparkling Aria and Shield Dust. I need someone to bring a Pokémon with Sparkling Aria and another Pokémon with filler moves. I'll handle the rest. I'll be available until [insert time]." If someone is willing to help, they could post a message on my wall.
You could place this thread near the mechanics research thread or the bug report thread.
PS - If someone has a Pokémon with Sparkling Aria and a Pokémon with Shield Dust and is willing to help, please post a message on my wall
