What Jim did is make a joke that anyone who knows anything about engine building knows was a joke. If they didn't know anything about engine building they should still know it's a joke by all the comments after his initial posting.
So when people considering what class to join hear about it, do you think they will ever see the comments about it? Or will they just see a copied and pasted ad? Do you expect most people considering what class to join to know anything about building engines?
Jim's joke set the class back, and if you can't see that, you're clearly qualified to be an HOA president.
