If you're looking for help about your Palm Pre, hopefully there will be many pages to help you here.
If you need help NOW, you might consider joining the discussion at our IRC channel. Come brainstorm with us at #webos-internals on FreeNode (irc.freenode.net) - same appropriateness rules apply - all chat logged. Not all browsers support IRC links, but never-the-less this should take you there: irc://chat.freenode.net/#webos-internals
if what you were looking for was detailed help about the wiki, we'll point you to the definitive source for that: http://www.mediawiki.org/wiki/Manual:FAQ
