if you didn't know already, xmpp is an instant messaging protocol that let's you talk to people on the internet, even if they're using a different server than you.
now, you can use that xmpp address to log in using your favourite xmpp client. if you don't have a favourite already, check out [gajim](https://gajim.org/) for windows/linux or [conversations](https://f-droid.org/en/packages/eu.siacs.conversations/) on android.
our server is [mostly compliant](https://compliance.conversations.im/server/southlondon.cc/) with the standards, so hopefully everything will work fine.
