[xAndrewx]

You'd add them in the serveroptions, then open their rights to configure their IP.
So if you were to hire me, you'd add my account 'xAndrewx' to the server options under the 'staff=' tag. You'd then open my rights by saying '/openrights xAndrewx' in the remote control chat. Once that has been said, a box should open up. At the top is the 'IP Range(s)' edit box, you can also add in the person's HD ID to that aswell as their IP. Either way add their IP or their HD ID, and then they should be able to log in to RC.

For their tags, you'd need to upload a text document into the FTP folder
levels/guilds/
You'd name the text document
guildNAT.txt
and inside there you would add something like this
xAndrewx: Snake
Account Name\Nickname
Giving me the tag 'Snake (NAT)'
