We're currently testing Movim at https://movim.uuxo.net — and we're happy to report it's working beautifully!

Two years ago, our HMAC-based file server wasn't compatible with Movim, so this is a big milestone. Now, everything integrates smoothly.

Feel free to try it out. The Movim team has created a feature-rich, privacy-friendly, and well-designed frontend for the XMPP network.
