I’d also like to see a little male/female sign under peeps avatars. I think there are a few folk here who are guys (I think) who have female Japanese avatars. Communication through text is easy enough to misinterpret as is, it’s even more so when you don’t know the gender of the sender. And yes that can make a huge difference in interpretation, especially when someone is trying to be sarcastic or cheeky.
As I said, it can make a big difference when interpreting what someone is saying. Not when they are asking or answering standard Japanese questions, but on the more social areas of the board.
