>>9>"compared to what I have seen"
Go look at some of the older introductions done by Kaori or Kannerz.
Now look at your own post. Compared to them, you sound like an absolute douche. I appreciate you giving them advice, but when you do it, try not to sound like a jerk in the process.
If this is what you consider 'being nice', then you shouldn't welcome people at all. (In my opinion, anyways.)
