I have been gathering information to create a tutorial on getting<br>
started, which<br>
is why I am asking the questions.<br>
<br>
For example, see: <a href="http://opensimulator.org/wiki/Configuration" target="_blank">http://opensimulator.org/wiki/Configuration</a><br>
<br>
Under "Standalone mode", there is the phrase "Grid Location". But this<br>
isn't a grid<br>
location because in Standalone mode one is not running a grid -- it is<br>
the location in<br>
something else: an Estate? Then, in the discussion of "multiple<br>
regions", there is<br>
discussion of "grid coordinates". All of this is confusing if one is not<br>
using a grid.<br>
<br>
Here is my understanding:<br>
<br>
An Estate is a set of Regions<br>
A Region is the same thing as a Sim (65,536 sq. meters)<br>
A collection of Sims (or equivalently, Regions) is an (Estate) ?<br>
<br>
These are logical distinctions, whereas, the term "grid" seems to be<br>
an architectural or physical distinction (i.e., how logical concepts map<br>
to physically located server equipment).<br>
