couldnt just check the forum "Introduce yourself/Real Life Picture Thread" for ratio gender?

It's sometimes hard to tell, or people will google image search appearance pictures to cover up their real gender ^^

There's no harm in having both topics, especially since people might be more comfortable with the "Gender Ratio" one because it doesn't involve including info about themselves or an image, just their gender~

Since the two threads have two entirely different purposes and focuses, they're going to get different types of responses to each. Not everyone is comfortable in posting their pictures on the internet, but a simple "M/F" question is not very threatening.
