I don’t see what you’re describing 🤷 Soon only appears once on the page and not in this context for me.

It appears as a tooltip here

Anyhow, where I intended to draw your intention was on prose.org/downloads

You can just download the client for your platform (assuming one is available), or use the web one (otherwise), or just build one from the sources I linked (which is what I do), and login with your usual XMPP account. Would you need an account and have to decide which provider to register with, this would come handy: providers.xmpp.net

In this set-up, prose.org isn’t hosting your account and will of course let you interact with thousands of users or more, like any other XMPP client.
