@Que,
This is an open forum that is gently moderated. You can use it to write eßsays. You will likely get feedback, whether it is helpful feedback or not is a matter of luck and subjective judgment.
There is a range of strongly held political opinions here. If you say something political, you will likely upset some of us and please the rest of us.
You can't sell things here. And threats and some blatant attacks are deleted by our overworked and underappreciated moderators.
Other than that, you can use this place for whatever you like.
I only ask that you be interesting... I like to be amused.
