How do you leave a Guild in Elder Scrolls Online

The option is a bit hidden; obviously so you don't do it by accident.

It's quite easy once you know it:

• Open the Guild with G (default keybind).
• Click on the name on the top left to make sure you've got the correct guild selected (since you can join up to 5 guilds at a time).
• Click on the Members tab.
• Locate your own entry in the members list.
• Right click your own entry and you should see the option to leave the guild.
