I really should visit this forum more often

Sorry about the app BTW - kinda don't have the time to develop it further (although for the record it's javascript and SVG

)
From my experience using wikis - establishing some kind of infrastructure is the best thing to do. Work out moderators, sections for them to use, ways for people to communicate about changes and problems.
I'll leave it up to Chad whether he wants to let folk know about the test environment on my website or not - I'm happy to have folks fiddle with that as long as they bare in mind that changes won't be reflected in the official Your Move Games wiki.
[edit] also - on the app - if anyone wants the sourcecode just let me know, I'm happy for anyone to develop or modify it.
