I don’t think that would be warranted yet - as far as I can tell there hasn’t even been a single topic here from an author using Adventuron wanting help. The sub-categories aren’t about keeping up a class system of IF dev systems, but are just an organisational tool for this particular website. Lots of popular dev systems don’t have a sub-category because there just aren’t many people here who use them. And that’s fine. This isn’t the only IF community forum on the internet, and if more people ever do come here to get help with Adventuron we can easily add a sub-category when there were enough posts that it made sense. If we added it now it’s not clear whether it would communicate “Adventuron is a first class dev system” or “Adventuron is a ghost town no one uses”.
Adventuron is listed in the “giant list of IF resources” link post. Do feel free to start a discussion in Development Systems (or any relevant category depending on content), or announce if there are new features or resources people can take advantage of.
There is already an Adventuron tag (I added it to this thread.) and it’s always good to have threads to direct people to when they do come asking about it or do forum searches in the future. We can always pin posts that become the de-facto FAQ about a subject.
I saw the “Next Adventure Jam” post and that’s a really good idea also. Itch is a good place for it - there is a lot of interest there in retro-style dev systems like Bitsy by people who might not overlap with the IF community here. (And this is not in any way an attempt to push you over there - on the contrary all IF/text adventure information is welcome and we should be so lucky that discussion blows up about any subject to the point we need to create a category for it!)
