How to change my profile name?

To change your profile name, click on your username in the top right corner of the screen and then select Edit my profile.

This will bring out a dialog box where you can edit your profile information. Depending on what permissions you have, you might see additional options here, but at the very least, this should let you update your name and email address even if you have the bare minimum of permissions.

Once you're satisfied with the changes, click Save and you're done!
