I've only used it once or twice before myself, and haven't been a fan of it. But after this and the last puzzle I think I'm gonna use it more regularly for my puzzles. Helps a lot catching cheaters, and not just people bypassing sgtools, but gives you logs for when people access different parts of the puzzle and so on, which means you can see if someone went through something way too quick or collaborate with time stamps from other sites to see who posted something anonymously, and such.
