Understanding SL

SL Agni Grid = SL Main Grid + SL Teen Grid + SL Beta Grid....is that right?

It is not possible to transfer items between grids. right?

SL Main Grid = Island Estate (private) + main land (Linden owned)

I found a gird named 'Local' in SL viewer. Is it also a Grid? I knew that Linden Grids are named after Hindu gods. But 'Local' is not a name of God I believe.

How many regions are there in Main land and in Island Estates? Is there any rate of growth of Main Land /month? Is that possible to get few details?

How many user accounts in SL and also their growth rate in past few years?

How much monthly transaction of Linden Dollars and if there any statistics of its growth?

Thanks for reading....

ugh.
