How can I add rank or change a rank in my guild?
Adding a guild rank can only be done by a guild master. In order to add a rank or alter any of the existing ranks, the guild master must click on the Guild Control button located within the Guild section of the Social window. You can open this menu by pressing 'O' by default, and then clicking on the guild tab at the bottom.
To add a rank, the guild master will only need to click the small red and yellow button located next to the "Select Guild Rank to Modify" drop-down menu. Each rank that is added will be placed at the lowest tier of existing ranks.
To remove a guild rank, there must be no guild members currently at that rank. A rank can also be renamed by clicking the "Select Guild Rank to Modify" drop-down menu at the top of the Guild Control window, selecting the rank you wish to modify, then clicking within the Rank Label area, renaming the rank, and then clicking accept.
