If every member of this forum sent you a welcome note it would take you a year to read the thread (about 121000 registered members) and I personally would be astonished if you did. Or perhaps the OP would like to suggest which sector of the membership should be responsible for welcoming new members so we can cut the responses down to around 1000
I've been a member here for going on 10 years and have a relatively low post count compared to some, I contribute when I can, shut up when I can't and work quite hard at knowing the difference.
I won't welcome you here because I only really visit two boards and "Introduce Yourself" is not one of them. I'll welcome your advice if you have any to share and you're welcome to mine if it's of value to you.
If that doesn't work for you, have a nice day.
