I have been considering running something similar to HentaiAndRoleplay here, however minor function that ends up being a major issue is at play in Lemmy; There's no in-built chat like Reddit, Twitter or (I assume) Mastodon have.

I considered adding an app like Sharex as the default program people would use, considering its quick to setup and discard, but then again that'd still require others to contribute to the community, and frankly from what I've seen, Lemmy folks aren't very chatty.
