The forum is separate from the chat application so what I'm stating here applies only to the chat rooms. Nothing has changed with the forum, and you don't need this software to use the forum, in fact the software is only for the chat rooms.
For years our chat rooms were flash based, but as someone in this thread mentioned, Adobe has recently announced end of life for Flash, and though they will continue it until 2020, it's already being blocked by default by browsers. Not to mention, there are so many random issues with Flash. And Flash doesn't really run on mobile devices. So the way to go, at least for us, now, is a mobile app and a desktop application, to cover mobile and desktop.
Thank you all for your patience and understanding in this transition and debugging.
Mac users don't fret, we'll be testing the Mac version of the desktop application any day now. Just pray that it works!
But besides just replacing Flash with a desktop application we are also making some important changes and additions to the chat system so hopefully it will be better in the long run!
