Hi @fulldecent! There was an All Core Devs call yesterday–these are (normally) scheduled every two weeks. The timing and agenda for the next call are published to http://github.com/ethereum/pm/issues and announced in http://gitter.im/ethereum/AllCoreDevs. Per https://github.com/ethereum/pm/issues/36 the next call will be on Friday 04/06/18 at 14:00 UTC.
It’s not clear to me whether you’re referring to an All Core Devs Call or to a Fellowship of Ethereum Magicians meeting (they are distinct). There has only been one Fellowship meeting so far, in Paris on March 9 (notes linked above). AFAIK the official channel for Fellowship announcements is this forum-- @jpitts/@gregc/@gcolvin correct me if I’m wrong!
