My suggestion is to run a telegram channel so when the greater community builds up it has a place to hang out besides this forum. Telegram tends to keep people around and gather more. There is no need to open slack in my opinion, it is be better to gather everyone in telegram and invite those who are active and willing to help.
ChrisB u didnt know ? so we need to inform about Telegram more if some of our old members doesnt know about it
That is true. The only link i have found (later on) was in the original ANN Thread on bitcointalk. But now it is also linked on the Website
