I was reflecting on this one.

Most of the threads coming up on repeat are fairly basic (they're newbies who haven't settled in yet). And we have a team of people wearing this 'greeter' sig, some of whom are also not actually very technical. I actually answered one of those threads yesterday - it was exactly the same as two identical topics on the same forum page. I just welcomed the poster, and offered him links to where discussion was already going on.

So if you see someone posting something basic that's already answered, just ignore it. Hopefully one of the greeters will get there - and be able to respond cheerfully however many times the question has been asked. It's part of what we're here for.
