Due to moaning from GodBen and some confusion as to Cal Fortuneswell's gender, the following code has been developed:

Standard procedure: Both parts should be contained within (brackets) and placed in your nickname after your name.

O-> means 'I am male'

O+ means 'I am female'

*-O means 'I have an ambiguous gender'

+O-> means 'I am both genders'

-O- means 'I do not have a gender'

oOo means 'I am lil / some form of gestalt entity¹'

O-O means 'I am 2legs'

:-O means 'Mind your own business'

In addition, the following optional code may be used to indicate species:

THS means 'Terrestrial Homo Sapiens'

TO means 'Terrestrial Other'

ET means 'Extra Terrestrial'

For example (O-> THS) means that you are a male Homo Sapien from the planet Earth.
