It is so blatantly obvious this would never work on such an immature board.
Making topics sticky that way is a terrible idea. Hot Girls thread on Off Topic would sticky, and that would be terrible for Badspot's reputation if it looks like he promotes the stuff we do.
People who post in help don't always know which answer is the best. They might mark one, then find a new post which is even better and simpler and not be able to re-mark it.
Limiting PMs to a certain amount of reputation will simply make a stuffload of topics trying to talk to specific people instead. Terrible limitation.
Again, limiting usage by reputation is a terrible idea. It will only cause massive frustration with the immature people here voting down for simple mistakes or misinterpretations.
Then it'd be worth a cent more than $20 to buy the game.
Taking the control to lock away from singularly the OP and Administrators is a terrible idea. You know how moody people get.
