Just a quickie, I have noticed people talking about 1 person fleets, but you need a minimum of five people to create a fleet in the first place. So do the other four just leave after or does the person set up 4 other 'dummy accounts' and then use them to create the fleet?

The other four leave.

Or you could create 4 "dummy accounts", provided you have enough terminals or a virtual environment to run the client 5 times.

To use dummy accounts, you'll also need to get them all past the silver account limitations. I think they need 20 hours played or a C-store purchase before they can help create fleets. Pretty time consuming and expensive, it's usually a better bet to round up five people and then kick them out afterwards.

What do you need virtual enviroments for?

The client can run as many times as you like without it...

I guess, if the machine can handle the resources.

If they are dummy accounts, just reduce the gfx on each one... who needs graphics for dummies right?

True...

Then again, if the machine can't handle the resource for 5 client running, probably couldn't handle a VM environment.
