Here are the questions:
1. What exactly is the impact of a 'region reservation' ?
-Does it increase your land tier costs immediately or only when you develop ?
-When you are ready to develop, what are the costs of "buying the region" ? Or do you already own it and start paying land costs immediately ? Or is the region actually "Island space" - and all you've done is reserve the right to build in that location ?
-Documentation is a bit vague - At first it seems like it is a parcel of land and once you win the bids, you'll get it as soon as it shows up someday. Some documentation makes it seem like it shows up immediately. On deeper reading, it looks like it's actually a placeholder to put an island down someday.
-Are you automatically the "Region / Estate Manager" for this region ?
2. Islands (using small as an example, that's all I looked at)
-$1250 setup, $195 monthly bill - that part was clear.
-Are you "Region/Estate manager" automatically for your island ?
-If you parcel up the island and sell off parts to other players, does your land tier rate go down ? Or does it always stay the same ? And do you stay as "Region/Estate Manager" ?
I'm going to go back and review the Island FAQ a 3rd time, maybe I missed something the first 2 times. Any answers here would be appreciated, though - I'd like to see about perhaps buying an island or region someday, but I don't want to do it and then find out I misunderstood what it's all about....

Thanks in Advance !
