You can create a username when you join STARTREK.COM, or you can log in and visit MY MEMBERSHIP to add a username to your membership.

Your username uniquely identifies you when you are visiting STARTREK.COM and participating in Community activities. If you did not choose a username when you joined, or you chose one but wish to change it, just log in and visit MY MEMBERSHIP.

Note: Once you have a username, you can change it but you cannot delete it.
