I have a board with two scenarios ready for publishing, and a third that's just plain stubborn -- it'll need more time than I have at the moment... I'd be working on it more later.

Is it possible to add a scenario after the board's published?

Absolutely, in fact you can update the "original" scenario after the board has been released.   Have you played any Dev games or checked out the Wiki on the subject?  If you haven't yet, you might want to invite some folks on these boards to play a Dev game before submitting the board for review.  Many on the review board regularly check the forums  ..or perhaps just point us to the design page with a link.

I've done some Dev games for review, and I'm confident with the playability of my completed scenarios.

Does this link work for you?

Oh yeah, I remember playing a Dev game on this board.

In fact, it’s pprobably best to publish (go live) before adding scenarios and then add them after. I just wish I could follow my own advice. 😩

It's a beautiful board Dubitty. Is it under review presently?

btw, you might want to go back and touch up the description. For example, I think one section shows as 'under construction', but I think you've completed construction on it.
