There are several custom fields in your profile which can be accessed by clicking the 'Profile' link on the top bar.

In order to edit your profile, click the cog wheel icon under the summary button. Upon scrolling down in the personal tab, you will find a drop down for the various races of Tyria. There is also a place to select your role (found here), add your character's pronouns, as well as your alias. In the alias field, we request you put your pronouns in parentheses alongside your name.

In addition, you are free to change your icon at any time.

An example of a finished profile can be seen below:
