In my activity I am focussed on GitHub and axisandallies.org, so I am not a frequent user of forums.triplea-game.org, as I must admit.
However, I am updating TripleA at least once a day and I am always using the latest (pre-) releases. I feel like already filling out the "test" role, as I regularly post bug reports / issues on GitHub. Honestly, I am not a fan of bug reporting to a (another) forum - as we do have those github issues for it.
During the past years I have helped out many players who had issues using TripleA. Not all issues are bug-related. So - if needed - I could help sorting out aspects that could be answered "quickly" on the forum from issues that should be moved to GitHub. Just an idea, of course...
Anyway - in case my activity can be of any help in the context of this thread, please let me know.
