Generic greeting that could simply be a copy and paste bit of text.
It's nice to see another person who is a tad bit older and the maturity that comes with the age. You don't give off any annoying or bad vibes, so I personally welcome you to the site, because I am simply that self-righteous.
In all seriousness, welcome, and have fun, here, and all that. Stick around longer than a week, please.
