Stickys have many functions. They convey rules of the board, pass on manufacturer recalls/safety notices (when members or mods are aware of them), are helpful to certain product/repair/tips/selling items FAQ's, and some are meant to head off really, really, FAQ's that by doing a search could be answered without rehashing the same Q for the xxx'th time. And yes, some stickys will originate from members, when decided they would be beneficial to the membership in general.
Marshal Stanton is the owner of the site, and of Beartooth Bullets. He funds the operation of the forums and the mods try their best to keep it operating appropriately.
