Welcome to The Escapist!
1. DO read the forum guidelines and read them carefully--there are infractions (such as posting nudity) which will get you banned in the blink of an eye.
2. Never call anyone 'troll', even in obvious jest--it's a taboo word. Literally.
3. The Escapist survives through advertising--as with 'troll' the word 'Adblock' is taboo. If you admit to using it (but fail to clarify "Oh, I, um, NEVER use it when I'm on this site--I always turn it off when I'm here" then you'll receive a warning.
4. How not to get banned [http://www.escapistmagazine.com/forums/read/18.391544-How-not-to-get-banned#15763320] is a handy thread for anyone to read if you're looking for pointers on how to--as its title says--avoid being banned. The list on the OP was built as the thread discussion went on. I suggest looking into it in addition to the guidelines because the discussions--including comments and clarifications directly made by Moderators--are enlightening. And often funny.
5. Ditto what the others said about being new here.
6. Stay out of the basement.
7. Those who know won't explain "why", "where", "what", or "Gods!!! We're all doomed!!!" about the basement. You'll have to discover the location truth for yourself.[footnote]Vault101 once went there...she's mad, you know. Oh, yes! She's quite mad.[/footnote]
8. Everybody eventually gets a Low Content Warning. It's kinda like a rite of passage.
EDIT: Feel free to answer any and everyone's posts. There's no maximum times etc limiting you. Also it helps posters avoid feeling like late night radio jockeys who spend their careers wondering if anyone's actually listening.
Plus the Escapist User Guide to Posting Commands [http://www.escapistmagazine.com/forums/read/18.198114-Escapist-User-Guide-to-Posting-Commands] thread will give you the site's basics for posting images, links, etc.
