To the contrary, there are many, many educators actively using Stencyl, but close to none enjoy participating in a forum format, choosing instead to correspond periodically via e-mail. If this weren't the case, I wouldn't be investing time into an Educator's Kit or putting up a subsite for education.
The challenge, correctly posed, is to figure out how we can seed a community of educators here, so idea exchange can happen. After the kit goes out, that's something I'll be working on.
