So when I haven't visited the forum for awhile... I like to do a quick click at the top of the response (replies) column to sort the threads by the number of responses.... if I see a bunch of threads with zero (0) responses I try to offer an answer or idea that might help.
When I joined the forum 7 years ago I asked a ridiculous number of questions and the patient, helpful members always gave me really good answers. I ended up with a very, very early "guru' tag which was (still is) hilarious. :)
So.. if the motto is "ask a question, get an answer" then no question in a category should go without some response.
IMHO... :)
