I think this might encourage too much OOC/IC blurring. I don't use OOC often and admit I kind of dislike it overall. I've seen a lot of not so vague questions or frustration venting that has felt manipulative oocly, even have been tempted or influenced by it myself or felt it complicated my ability to rp well. It's excessively frustrating when you've poured a lot of energy into a scene or rp, only to have someone vaguely complain about it ooc and there's no way to engage with the convo but it stirs up other people.
On the other hand, people like me could just stay away from it. I'd just want to make sure it was heavily monitored. Maybe a few of the discord moderator people could work to help in there too? I don't remember how that all works. I think the forums are better for thoughtful conversations on the game that admins can engage with, but maybe I'm just heckin old.
