Are there any groups of active Classical Latin users nowadays?
By active I mean they meet regularly and speak in classical Latin, or make some videos/vlogs/podcasts or present lectures.
There are Nuntii Latini, of Radiophonia Finnica Generalis, who bring Latin news. I don't know whether they are still active, though. E.g., here on the arrest of Ratko Mladic: http://areena.yle.fi/radio/1278942
There is also the Bremen Latin news: http://www.radiobremen.de/nachrichten/latein/
EDIT: The French website mediterranees.net/latin_vivant.html has many links, including both of my above.
Thomas Bervoets, whom got me into classical Latin in the first place. I recommend listening to him the most:
The Finnish female Classical Latin news announcer of the Finnish Nuntii Latini: https://areena.yle.fi/audio/1-1931339
And the lady on YouTube video called "Classical Latin VS Vulgar Latin- What's the difference?" saying the Classical Latin sentence "Marcus patrī librum dat."
