The +invite system lets players warp across the game to directly join other players no matter where they are.
+invite <player> - Extends an invitation for another player to +join or +summon you. Invites expire after 10 minutes. +join <player> - Warp to a player, or extend a request for <player> to +summon you. You can also +join to someone if they are within reach of +port. +summon <player> - Bring <player> to you, or extend a request for <player> to +join you. Staff can skip the invite process and simply join or summon players. However they can still extend invites.
The Grid system is a series of commands that make it easy to navigate the IC rooms, or 'Grid.'
ooc - Teleport to the OOC Lounge. ic - Return to your last IC location, or the IC Nexus if that fails. +nexus - Teleport to the IC Nexus. +roomlist - List all IC rooms in the game that you can +port to. +roomlist <search> - List all IC rooms partially matching the entered text. +port <name or dbref> - Teleport to a room. +sethome - Set the current location as your 'home.' +gohome or home - Teleport to your home.
Players using THINGS as hangouts can make that object a valid +port destination by setting its PORT attribute to 1. Use &PORT here=1 while within the object to set it.
PENNMUSH: You must also set @lock/teleport here=#TRUE - Penn users can use @lock/teleport to restrict who can access the object with +port. The Lock Management System is installed and +lock is available for this. See +help +key
