Provide a way to easily determine the PC's gender
... set when the character is created.
This could be a static GLOB or a function like
getGender <oID>. AFAIK there is no way to get the gender of the PC except forcing a conversation to the PC (PC has to "use" a topic).
I prefer a static global variable - probably faster, if not, a function (prevents messing with the value). Some may want to mess, though - setGender (and getGender) in that case.
