This may have been suggested before but I thought I'd throw it out there.
How about a FAQ thread at the top of the forum. You could list out all the FAQs like MPG/performance mods, Average MPGs, what size tire, what is my bolt pattern, which leveling kit should I get (2", 2.5", 3") and why, how do I post pictures, how do I upload pictures, etc... And the very first one could be how do I use the search button feature!!
It won't stop all the multiple questions on one topic we get but it may get a lot of them. Or we could just point all the askers to that thread.
