Welcome to the forum! About time you joined the fray!
Your questions are welcome here, but before you ask a bazillion questions, download Ed Felker's excellent crowd-sourced manual for Vegas/Axis. Find it as a sticky in the main menu under the "Tech Topics" section. You'll find answers there to questions you haven't even though of yet!
He just released an updated version. Priceless!
May the trails always twist in your favor
May the tales always end in good light
May you have more friends than one campfire can hold
