Just do it. /help market. Update that, it still has the old /market create price amount. Add the link for market rules. Its been months, shouldn't have an oversight like this.
He mentioned market, not shop. Either way i believe we have to await his response instead of guessing.
Its on the crackpack server, maybe on the other servers too. I'd have to download a few modpacks to check though, and I'd rather not. Its just hard following the market rules without a way to find them without sifting through the forums.
To be honest it really is only two links for the market rules. Rules - MineYourMind 5.0 And a list of the end game items for every server.. Endgame Items | MineYourMind Community
I feel like thats a bit vague to be the guidelines for market. And another point of this thread is to get rid of the useless commands /help gives you and replace them with the new ones.
