My suggestion is that we add a /help mcmmo. In it, we could have a /help mcmmo excavation, and it would tell you what drop you could get for each level, such as a list like: 1-49: No Drops 50-249: Glowstone Dust 250, etc. etc. and just keep explaining what you could get. I think we might have this implemented into /mcmmo help, but i think we should have this, or add it to /mcmmo help
I Like the idea of having a "/help mcmmo", but having an "/help mcmmo <sub section>", to my knowledge, doesn't work with the way the log in message and /help work. That part of essentials doesn't support sub sections yet. This would be up to KHobbits to code it. But yeah, I love the idea!
