The only way it tends to upset me is if I see it, say posted at 10:00 then on another forum at 10:15. I try to limit myself to two forums for most of my stuff though do belong to a few others, i.e. the Ford Truck Enthusiast and Ford Forums for my daily drivers. I also try to choose which one I post a question - for instance, paint and body work isn't the strong point here but another - great. Occasionally I'll post a question on a forum, get either no answer or ones that are I know for sure, wrong, then may go elsewhere - but not the same day.
