So you've made a portal for the guy who gave you 3 gold. He went through, and now it is just sitting there, useless. Only one player went through and you got more than enough money to cover the reagents. So why not open it to the public?
PortMe is an addon designed for portal invite management. It responds to the phrase 'port me' in various channels.
If there is a portal active that has already been paid for, it will notify nearby players that they may use it. When they say 'port me', it will notify them of the entrance, exit, and duration until the portal expires. It will also invite them to a group.
If there is no active portal, it will tell them your location.
If you are already in a group, and cannot invite, It will notify them that no portals are available at this time.
Notify's nearby players after a successful portal spawn
Notify's Pary/Raid members of exact portal location (including coordinates if available)
Invites players who whisper the trigger word while the portal is open
Pings Minimap upon portal creation
Will not advertise or invite if you are not capable of inviting
