Moving this over to the forum help board
And depending on what you mean by "complaint"... if you'd like to discuss a normal thing in-game ("why are there stereotypes?" etc), you may go to the game discussion board and post there
If you mean here on the forums, then the same thing above, really. However, if you're wanting to complain about something really deep/that should be kept off the forums/etc, then I ask that you really consider whether or not you really want to share it (if it's against the board rules then refrain from posting it all together). We aim to keep our forums safe and friendly for everyone, but of you're not sure about a topic, then you're more than welcome to pm myself or another staff member
