I don't like trainers because of what they are designed for. Many people don't use them in bad ways, but many do. While I know you would never cheat, having yet another trainer in circulation could create additional problems. I suggest that you do not send that trainer you are creating to anyone at all, not even people you trust the most. Hopefully that's obvious though.

I suggest pooling your programming talents into something that can be of use to people. There are many types of programs that can be made which are not considered illegitimate, such are server utilities.
