Things like Cards Against Humanity can be played but would need to be customized for the community - perhaps a wizarding version could be made!).
They actually have something like this already! It's called "Cards Against Muggles" :3 You can look it up and see because I dont' want to risk link posting here but it's pretty amazing.
I would also be more than happy to have a voice chat, if only so everyone can laugh at my butchered British-American-Malaysian mess of an accent.
A voice chat would be so fun. We'd get to know each other better and bond through all of our different accents. I use voice chat all the time for gaming and it's like being able to talk to someone on the phone without dealing with an expensive phone bill. I know discord DEFINITELY has this option.
Here are a few suggestions or events I think would be fun for community bonding. They would be, of course, optional to participate in.
1. Using Discord Voice Chat for chit-chat, story telling, and playing video games together. I noticed a lot of us play blizzard games. ;)
2. Skype or Google would be good for Video Chat or where we can hold Video/Audio virtual meeting rooms which would allow us to play card games, live script readings from books or plays, ect.
3. Community Movie nights. I hold these for my twitch community and closest friends through a web based platform with screen share survices that allow the host to stream through sites like Hulu, Netflix, Crunchyroll. ect.
