I have an XMPP/Jabber server. It features OMEMO encryption. I run it from a closet in my house. It is up if my house has power and internet (so, most of the time.) It allows uploads of pics and video for sharing. Those files are deleted after 24 hours.
You can join it by using "Conversations" on Android, or "Siskin IM" on iOS, to create a new account at thraeryn.org
If you do, please let me know your user name! I am, as one might expect, firstname.lastname@example.org
