I'm afraid something happened to our hosting provider, Heroku, and CommunityWalk is currently down. We are talking with them about it, but if they are unable to fix it then we may have to shut CommunityWalk down. If that is the case we will refund all users their last payment. I hope it won't come to that, but at the moment we aren't making much progress with our hosting provider.
I apologize for the inconvenience this is causing people. It came out of nowhere just the other day based on changes Heroku has made. At the moment if Heroku doesn't address the ramifications of those changes then we likely will not be able to get CommunityWalk back up and running.
We will post more in this forum as more information becomes available.
