Seeing as you want some updating, can I recommend:
Lord Krunk's 'The Banhammer and You: A User's Guide to the Forums' Thread [http://www.escapistmagazine.com/forums/read/18.112832#2019333] As the mods say: Not the official rules, but it's a damn fine user point of view look and guide to the rules.[footnote]I know you said you wanted to include this in the actual thread, I just felt it should be mentioned here as well.[/footnote]
Nomad's 'Hitchhiker's guide to the Escapist' Thread [http://www.escapistmagazine.com/forums/read/18.147439#3392143] A nice and handy guide to the content on The Escapist for lurkers and users alike who feel lost on this site. Just remember to bring a towel.
NewClassic's 'I Bet He's Cockney II: Rise of the Machines' Thread [http://www.escapistmagazine.com/forums/read/362.143644#3217202] Find out who the men behind the avatars are. Accuracy optional.
Scotth266's 'Your Review And You: Welcome to the Review Section!' Thread [http://www.escapistmagazine.com/forums/read/326.120165#2350144] Like Simulord's Review Advice Thread, this is a handy guide for writing reviews and the review forum in general.
NewClassic's 'NewClassic's Writing Theory' Thread [http://www.escapistmagazine.com/forums/read/18.111856#1972468] A very important guide to writing in general from the Vault Legend himself.
Higurashi's 'Escapist role-playing and you.' Thread [http://www.escapistmagazine.com/forums/read/362.116378#2173871] A detailed guide to RPs and playing in them. A must-read for every keen RP'er.
I may think of some more over time and I'm not sure if some of them have already been mentioned. If you need some Genre Wars threads, [user]bodyklok[/user] made a community map specially for Genre Wars here [http://www.escapistmagazine.com/forums/read/376.107708]. Feel free to take stuff from there. Also feel free to change the descriptions, I'm not feeling imaginative tonight.
