The first time I made a positive contribution to Wikipedia (years ago), within minutes a senior user left a comment on my user page welcoming me to the community and thanking me for my contribution. He also told me to contact him any time if I ever need help or clarifications. As a result, I felt like contributing more, and I avoided a number of newcomer gaffes.
Should we have something like that here? Sometimes, I notice that the first experience a newcomer has here is to have older users tell them that their question is off topic or poorly phrased. Some of them may only get around to reading the policies in detail after a few day of participation. So, shouldn't we help them avoid submitting poor questions/answers?
