With the new release and upgrades, the non-binary gender markers are again available.
Besides "Male" and "Female," we now have "Intersex," "Androgyne," "Queer," and "Questioning."
If you have 15 or more posts, you can modify your Forum Profile to show a gender marker - it is entirely optional.
On your Tool Bar, click on "Profile" and then on "Forum Profile" from the drop down menu.
Scroll down to the "Gender" field and select an option from the box. If you have a marker, and want none, select the blank top line.
When you are done with the selection, scroll down to the bottom right and click on the "Change Profile" button.
If you need help, just contact me by PM, or send me an email with your request. I can put one in for you. 🙂
