Please be nice to new members.
Please don't jump down the throats of new members.
Please don't scare away new members.
I know that we are the old hats here, and are experts about everything, and really are never wrong about anything. This is, of course, completely true.
But we've all been on sites where the old guard jumps down the throats of newbies, and those sites suck.
Let's not become that site. Everyone was a newbie at one time. Fresh blood is good for the conversation, good for the discourse.
Please don't make us have to legislate this problem away.
