Hi Garry,
Welcome.
A word of warning - this jam is trying its best to be very inclusive to beginners that are perhaps not looking for the full gamut of features that are present in the Inform 5 .. 7 systems and indeed might have no concept of some of the advanced features which older players and authors have become accustomed to.
Just like the vast majority of Microsoft Office users don't use the vast majority of Microsoft Office features, when designing classroom, I figured that it was worth just focusing on the core features of an adventure game as a way of bringing new talent into the fold (not scaring them). I also lean on the styling features that were present in some 80s toolkits (such as QUILL / PAW / GAC) but less present in Infocom games (despite Infocom's more advanced internal features).
As an expert, it may be that you end up disappointed with Adventuron, in that is quite different indeed to Inform, and less advanced in many ways. I do hope you enjoy yourself though, and that, even though Adventuron might not have ALL the features of Inform, that you learn to enjoy its unique features, which might be more than appear at first glance.
