@Tom, @cklester, I might not have been specific enough. There's a discussion forum in the Construct Classic forum section where people can (but typical don't) request tutorials, have more in-depth conversations about existing tutorials, announce work on new tutorials to solicit input, etc. Right now, if you want to do any of those, there's no truly appropriate forum. General/Tools-Resources or General/General-Game-Design are probably the closest.
I'm not at all suggesting putting tutorials themselves in the forum.
