For the original starmap:

	Everyone runs OUTBOX, including the person who'll be merging them. All the outboxes are sent in.

	The merging person runs CreateInbox (inbox32 compiled with the MERGING flag). 

For Starmap3:
	Put your starmap3.map, starmap3.gd, starmap3.usr, and sync-starmap onto a computer with internet access.
	Run sync-starmap. It will get http://noctis.sl.ecwhost.com/starmap-version.txt, and will read the version, then generate an outbox, and then start requesting inboxes from the server, and as it gets each one it will apply it. It will tell you to send the outbox to starmap at noctis dot sl dot ecwhost dot com.
	The person doing the merging puts the outboxes in the noctis\data\original folder and names them outbox.7z.001 etc. Then they run CreateInbox3, which will do some really cool stuff to make an inbox and merge the changes into the starmap3.map and starmap3.gd and starmap3.usr files. It also updates starmap3.svr, which is the server's list of users and passwords.
