hard to comment on Discord without sounding like an old fogey

In the real world I have to use a lot of these tools - Glip, Slack , Discord.. <old mode> each has a place but none really have the structure that I would look for to use as a repository of any information. Lack of nested info 'streams' etc </old mode>
They all just end up being a messy 'chat' unless you have super discipline.
Discord is great for online gamers who want a stream of text chat and video chat... but is that what you want from RFCM?
On the plus side - it is free...
