To put it simple: Uh?
Okay, what I could get from your post is that you think we should focus more things about the campaign since some members only come because of it.
Firstly, not some, but almost all are like this.
Secondly, there are already many topics completly related to the campaign in another forums besides the Off-Topic. Yet, if you think something is missing, you can always create a new topic.
Thirdly, the essence of Off-Topic is: Let's NOT talk about the campaign or, at least, not in a direct way.
Fourthly: A "Did you know..." about the campaign would be a spoiler thread basically. Besides, you should have, in theory, complete knowledge about everything in the campaign once it's complete. You just have to play it.
For example, "Did you know that Galeoth is gay?". Perphaps he is(not that I know), but since it's not revealed until ch. 10 we don't know. Aero would be the only one that could post also, since he's the one that knows the story. And to talk about the story of the campaign that we, the players, know it's completly unnecessary since we, in theory, should know all of it
.
"And what about 'did you knows' that weren't shown in the campaign?" Again, only Aero would post something
. And I think that would be really wrong
