my response is based on I’m a complete noob, lots of people had read the post which asking a simple question and I would guess 75% view could have taken the time to answer. There is no way to build a responsive support community if only 2 or 3 people are answering all the questions. I have a some experience with phpbb3 and a little with SMF& Joomla, the questions at those support sites usually get answered quickly. Hard questions could take days.
The main point it is blessed are those who give, not just receive.
