Oddbean new post about login | logout I don't really understand why it's not a relay. But also, why not try this client method ¯\_(ツ)_/¯. Relays are kinda the trickiest part for new users to understand (I also still don't understand tbf).
There is no client that exists that has the tools we need at the moment.
Maybe @Pablo Xannybar has seen already, but might be his kinda thing. ¯\_(ツ)_/¯
