We're moving to slack. Well, the team is already there actually. A problem with slack is that people needs to be invited to it, so they can't just join the team. Luckily there's a few plugins for slack that can handle this invitation automatically. The job is to find the best one and integrate it in our page. Since we use dokuwiki we think it's going to be really easy to integrate, even if you don't know HTML. All you need to use is well documented and what you have to do is put pieces together.
