You can change this, by the way.
Click on “My Account” in the upper left corner, “Forum Account” on the left (may be near the bottom if on a mobile device), “Edit Profile” next to “View Profile”, and then under “Last Name”, there’s an option that says “Public Change“. Click on Change, and you can restrict who can see your last name – Public, All Members, or Only Me. Then, click “Save Changes”.
(There’s also a nickname choice but that doesn’t seem to be used…)
