why would u create a discord and a slack? isnt it a way better idea to create one place for the community to get to know eachother, hang out and get information from?
Everybody has their preferences and we got multiple requests for a Discord chan. Some people refuse to use slack and visa versa. Our communities require very little moderation because of the awesome people we have in them. So it's really no extra work, plus I actually prefer Discord over slack.
What about using telegram? I see several projects have been moving to telegram also because of spamming & scamming in their slack channels.
