OK - hit a snag trying to deploy my test app to heroku. This may need to be in a different location, maybe a formal github issue, but will start here:
I followed the very helpful wiki entry at (https://github.com/designcreateplay/NodeBB/wiki/Installing-NodeBB-on-Heroku)
Got to Step 8:
me$ heroku labs:enable websockets -a guarded-basin-1356.herokuapp.com
Enabling websockets for guarded-basin-1356.herokuapp.com... failed
! Application error
Everything seemed fine up to that point, and I checked this Heroku help page (https://devcenter.heroku.com/articles/node-websockets), and seemed to work - I got the local app to work ok from:
me$ foreman start
So any ideas? I may just try a different hosting cloud if this isn't an obvious fix.
