@NullNowhere Adding voice isn't too hard with mumble. The big limiting factor is that it's just a lot to maintain as the group size increases, and folks are _used_ to doing things all in one app. Telling them "You need to download these two pieces of software to participate" when previously they had to have _zero_ extra pieces of software (since they already have a browser) could be a hard sell.
If you need to do it for a gaming group of, say, a couple dozen people, it's probably doable by one person. Source: I've done it, and I've set things up for folks who are _not_ computer literate to manage, too. The "maintenance" is really a form of light IT work; people will need help setting up the software on new computers as they get them, stuff like that. A solid PDF on how to set things up will work wonders here.
If you have a community that has a couple hundred people, my recommendation is definitely to pay for something, and it'll likely be web based, which is a plus, obviously.
I'd love to see foundry's builtin services get better, though. I think the problem historically has been that they've leaned on the fact that discord existed to not have to work on it, but I suspect they're going to need to address the quality pretty soon.
