Maintaining and strengthening staff's stance on gender identity, it is still our belief that your personal discretion when using the non-binary request forum as opposed to the male or female is appropriate. If an issue does arise, please report it and staff can handle it on a case-by-case basis but otherwise we're not here to label or determine what is non-binary and what isn't.
Sync and Vi are correct in that the different request forums are categorized by the character you intend on writing as - I appreciate that your heart is in the right place for following the rules however I would value your comfort and inclusivity more in a situational nuance like this.
