Thread:Extension talk:GuidedTour/Coordination with the Wikipedia Adventure/reply

Yes, E3 (including me) has talked occasionally with User:Ocaasi (developer of Wikipedia Adventure). We've also kept people posted publicly, including on the EE mailing list, Wikipedia Village Pump (e.g. here), Wikinews, and Wikivoyage (original discussion, GuidedTour Tour Agency under discussion).

As far as documentation, we have Extension:GuidedTour/Write an on-wiki tour. It's a start, but there's definitely room for improvement, and we need to put some time into that. We are planning to do some refactoring of the extension soon, which may involve some changes to how tours are written (we'll help people make the needed adjustments). So there is nothing stopping people from writing tours right now, but it may not be the ideal time for a big push.
