Questions about Beta Test Grid

I just went in the Beta test grid and have a few questions.
#1 If i buy a object in the beta test grid will it come out of my main grid Linden balance?
#2 If i buy land in beta test grid will it come out of my main grid Linden balance?
#3 If i buy land in the beta test grid will my land teir go up?
#4 Why do I have so much linden in my Beta Test Linden balance?

I also have see the Edge club in the beta test grid that is set up the same as in the main grid.
#4 Is it really the same club or have it been built the same rentals spots and all?

Thanks!

The beta grid is to try things out. Nothing you do there should carry over onto the main grid.

I think you get a +5000 Linden bonus on top of your "existing" balance, probably to encourage you to go on a splurge and try more items and find more Bugs.

what happens in Beta, stays in Beta!
