If we had a sticky for oft asked questions, CoffeSnobs discussions would decrease by 50% and the number of threads would explode!!!
When people ask the same question as has been asked before, often it is a way for them to dip their toes in the water with posting in a forum that is new to them - this is how I became a CS member, many moons ago. The replies that I got were so personalised and helpful that I continued to visit the forum and it wasn't until being on here for a while that I realised that my question was one that had been asked many times before!
So, I guess, what I'm saying is, treat these questions as an opportunity to provide some of your wisdom and knowledge, and to get to know a person and welcome them - it only takes a couple of minutes to reply but may lead to a lifelong friendship.
