PSA to all hosts

So, recently there's been a couple competitions with... Major issues.
Some of these competitions had dumb rules from the very beginning,
Some of these competitions had major rules being made after people had built and sent in cars,
Things like this make me want to slam my head against a desk repeatedly. Please, for the love of christ, if you're going to host a competition please make sure that:
1. Your rules aren't insanely restrictive
You get the idea...that may have been slightly exaggerated but you get the point
2. You're not making up rules mid way through the competition that will drastically affect how the competition will play out, especially after people have already sent in cars.
That will be all for now.
