I think you should be able to do something like /plotme chat so that if you have multiple helpers helping on a plot you can talk to them, tell them what to do, etc. Let me know what you think!
I like the idea but the PlotMe plugin wasn't coded by our developers so it may be rather hard to implement directly into the PlotMe plugin. Correct me if I'm wrong.
Great idea, not realistic though. Since the PlotMe plug-in itself doesn't have the command, a new plug-in would have to be developed. This would have to be compatible with PlotMe and receive information from it. Not the most efficient thing to solve the issue. The realism depends on how good Tanner is, and to be honest, even if it's easy to program, there are alternatives that require less effort. Just use /msg and /r or a Skype chat. On that note, No support. Sources: http://plotme.worldcretornica.com/cmdsandperms.html
