If you need to change the gender that is associated with your profile, you can do this by logging in to your forum account. Once you're logged in, click on the Profile button typically found in the top menu bar of the forum. Once on your profile page, click on the Edit Profile button and you'll be brought to the Edit Profile & Settings page. Click on the Personal tab and you'll see Gender listed as the second option on the page. Select either Male, Female, or Other/Decline to State depending on the gender that you more closely identify with, and then click on the Save Personal Settings button located at the bottom of the page. After the changes are saved, your profile will be updated with the gender that you have selected.
While setting your gender is a requirement for your forum account, you can choose whether or not you want your gender to be displayed to other members of the forum. This includes forum staff members as well. To determine whether you want your gender to be displayed or hidden on your profile, click on the Profile button located in the top menu bar of the forum, and then click on the Edit Profile button on your profile page. Once you're taken to the Edit Profile & Settings page, click on the tab for Privacy. You'll see the first option on this page read Show Gender — set this to either Yes if you want your gender displayed to other members of the forum, or No if you want to keep your gender to yourself. Once you have set this, click the Save Privacy Settings button found at the bottom of the page. Your selection will take affect immediately after the settings have been saved successfully.
