I think these should be added to the list of staples:
* What's the best Olde Skool (tm) setting / module / whatever? (a.k.a. the old timers make you feel bad about not being as old as they are)
* How should I interpret this vague, poorly-conceived rule? (generally confined to the Rules forum, here)
* I found a great price on product X at Wal-Mart / Amazon / OtherLargeFacelessCorporation. (usually followed by huge flame war about why you should support you Friendly Local Game Store (FLGS) instead of Wal-Mart, etc.)
* Please help me solve an intricate plot / role-playing problem in my incredibly detailed campaign that takes twenty paragraphs to explain. (sometimes these die after no responses; other times they blossom into something cool)
* My spouse / significant other / parents / friends / church don't like me to play D&D. (usually followed by a massive flame war)
* My gaming group suxxors. (following discussion will be evenly split between "ditch 'em and find other" (even if the poster lives at an Antarctic research base) and "work it out and quit whining")
* How do I convert Batman / James Bond / Luke Skywalker into game stats? (pointless argument ensues)
* Help me munchkinize my PC so he can do a lot of damage / have a lot of hit points / cast a lot of spells / be uber. (the WotC Character Optimization board is better for this, but it comes up in the Rules forum here also)
