My googlefu is low tier all I kept finding was people asking on their forums if they could get a discord chat box lol.
The magic search phrase was "embed discord". When it comes to Googling, think simple.
Re: shoutbox; I think a valid point is being raised. Do we want to consolidate communications on and around TLS, or are we okay with siloes?
I mean at the moment we've got the shoutbox, forums, and Discord. There was one, if not two major Skype chats, but at least one of those has died recently (after months if not years of poking "hey maybe we should stop and go to discord". There was also IRC, similar story. Facebook groups / group chats have formed recently around the Kupocon wossnames and s00per s33krit conspiracies (although they tend to die off after the event).
On the one side, consolidation good, one close-knit community, etc. On the other hand, fragmentation is good too, since it allows smaller groups of people to get to know each other better. In fact, TLS' origins can be traced back to a splinter grouping off of ACF that shitpoasted on FFOF, one of many splinter forums that branched off of ACF at the time. I think that while we can idk, close the shoutbox in favor of promoting the forums or discord, I think it's pretty sure that people will naturally form chat groups outside of the main site. I'm not going to tell people to not do that.
