I see the exact same question come up a lot - sometimes a couple of times a week - usually from newer users. Of course, they want answers to their questions, but by asking a question that was just recently asked, they may not get the same range of answers either. The search feature is what they need, but I'm not sure if everyone is aware of it! Perhaps a message at the top of the screen, when you go to post, reminding people that the search function can turn up a ton of information quickly, without waiting for others to post their responses??
Alan and Denise, any thoughts on this?
