In the past few years, our Facebook Group has served us well and continually do so. It’s a nice forum, easily accessible if you are in Facebook anyway, as probably most of us do, but not so for those who wish to avoid social media and all the issues that go with it. It also tends to be too cluttered and noisy. The discussions cover a vast area from Guitar building to Digital Signal Processing. There are no focused chat rooms that you can join for specific interests.
We value meaningful discussions and we are very open to collaboration. For an even more engaging experience, and without the issues associated with that social media giant called Facebook :-), we now have a slack forum. The Slack platform is an excellent collaboration hub with chat rooms for specific topics for various areas of interest.
