I think you can get a list of them by typing /help normal in-game, or, atleast you can see some of the main ones you'll need.

To invite a new member:
/guildinvite <name>
To make a new officer: (they must be a member first, I believe.)
/guildinvite O <name>
To make a new message of the day:
/guildmotd <your message here>
To guild Remove someone:
/guildremove <name>
I think to pass guild leadership (if it still works) is:
/guildleader <name>
