What are all the commands for members? Not just the commands you get with "help" thing, but the buying, selling, locking etc.

If you type /lwc (locking commands) and /shop help (shop commands) those will give you all the commands that there are to members on this server. They also have some guides on the forum. If you would like you can also go to the spawn, they have some guides that are being made in the different buildings.
