How?If i'm correct you are already able to setup a message whenever someone enters faction territory. I also believe this message shows up whenever you log on.
It's called time zones and people having social lives, check those out next time.They call it the Friends plugin, you should check it out next time.
From the Changelog, Cay is presently working on the Mojang UUID change and MassiveMobs. He also has plans to expand the capabilities of MassiveQuest in support of a new Quest world map that is being developed. Which project will follow these is still being decided.It would be useful however it has been stated by members of the staff that all other plugin development is on hold until the MassiveMobs and (idk what its called) the MassiveMagic plugins are finished.
