Thank you for the link, I&#x27;m watching the video while I write this message.<p>But - I just checked again: My xmpp server of choice (Prosody) doesn&#x27;t support MAM today¹. That&#x27;s a killer, without that xmpp isn&#x27;t even in the same league as WhatsApp, Telegram etc. for me. I expect to be able to open my client and be able to continue a conversation at this point.<p>1: There&#x27;s <a href="https:&#x2F;&#x2F;modules.prosody.im&#x2F;mod_mam.html" rel="nofollow">https:&#x2F;&#x2F;modules.prosody.im&#x2F;mod_mam.html</a> but it is unclear if that&#x27;s in a usable state. It states at the bottom of the page that this &#x27;works&#x27; for 0.9 and 0.10, but the &#x27;storage backend&#x27; sections gives an example that works for 0.10 only and links to <a href="https:&#x2F;&#x2F;prosody.im&#x2F;doc&#x2F;storage" rel="nofollow">https:&#x2F;&#x2F;prosody.im&#x2F;doc&#x2F;storage</a> where you&#x27;ll find a table with backends. ONLY the &#x27;sql&#x27; backend seems to support the archive store, and that&#x27;s for 0.10 only. 0.10 isn&#x27;t released yet. The takeaway is: MAM seems to work if you&#x27;re using the unreleased version 0.10 of prosody. And .. I haven&#x27;t even checked the client support yet.
