Hello, I'm new here. I can't claim to have lurked as I only discovered the site a few days ago.
I've entered the sitcommission thing as is my won't (those are some electrons they'll never get back).

Hello!
Welcome and hello. 
Hi there and welcome. 
Hello there.
Greetings.
Hi

Welcome and shit.
But not on the carpet.

Ahoy hoy!!!
Hello there
