Considering that "posting in the Indie Game Design forum implies that you're a commited designer, etc.", where would it be appropriate to announce that some work-in-progress has met some completion or milestone? (To show that you were commited and made something of it, but not necessarily to discuss some technical aspect.)

Hi Dev,

The answer is "yes," but with the always-present proviso that Forge threads are intended to be discussions. So your best bet would be to present the work, or part of it, for people to see. If you don't want to do that, then you could also describe the problem you managed to solve and how you did so.

Such a thread is golden for Indie Design.

Best,
Ron
