Welcome! You'll no doubt find the board can get touchy over certain subject so, to avoid accidents:
1) While you're finding your way around, read and use the search (it doesn't work well, but still try) - most questions and topics have been brought up several times and you'll get an idea of opinions and what's what on the forum.
2) Have fun!
Bonus: Join the Off Topics section for shenanigans.
Bonus bonus: If you have infinite amounts of money, or like spending your last cent on guns, join the Equipment Exchange. Your wallet will never be the same, and you should also buy a spare gunsafe in preparation.
