Re: Be kind, rewind!
I know I'm newer than a lot lot lot of people on this thread, so when someone asks a question that I don't have experience on, I tell them so. "Here's my two cents, but you'll probably want to hear from someone who knows better." I haven't been around too long, but even I'm starting to notice the barrage of similar questions.
Senior members have gone out of their way to make detailed posts of information concerning things like different kinds of hookahs, tobaccos and bowls, so perhaps gently suggest a search or direct them to those posts.
