1: No spam or advertising. This basically means no linking to your own content on blogs, YouTube, Twitch, etc.
2: No bigotry or gatekeeping. This should be obvious, but neither of those things will be tolerated. This goes for linked content too; if the site has some heavy "anti-woke" energy, you probably shouldn't be posting it here.
3: No untagged game spoilers. If the game was recently released or not released at all yet, use the Spoiler tag (the little ⚠️ button) in the body text, and avoid typing spoilers in the title. It should also be avoided to openly talk about major story spoilers, even in old games.
I never actually played this at home. They had it on our school computers and it was a mainstay of the day.
Our elementary school computers had one copy of Odells lake on a 5 1/2 in floppy disk and some copies of Oregon trail to share.
We had crab volleyball on our high school computers.
