Well, ideally I'd like to establish the rules/etiquette that while it is open for more casual chat or quick questions, it's not supposed to be an outright replacement for the forum.
My general thinking is that if you post a new character on the forum, then it would be okay to chat about it on the Discord, but it's then only polite that you come back to the forum and say "Following discussion on the Discord, I've changed X, Y and Z", for example.
Similarly, quick questions about what colour to paint a character's hair is fine, but it shouldn't be the only place you're providing project updates.
It does of course have the potential to eat traffic from the forum, but when it comes down to it, the objective of The Conclave is to support the Inquisitor game, not to support a forum. If we can develop a stronger community, then we need to look at how we can improve.
And, in any case, a larger active community will benefit the forum, even if not everything happens on the forum.
I'll start looking into it, but I'll need to do some thinking.
