I'm writing from Nostrudel, but only Amethyst does isolated-writing. 

 is isolated-writing where only authorized npubs can write and read, not just write? 

 No, I mean, where you can select which relay to write to in the note. 

 ahh i see. i think coracle also makes that pretty easy. nostrudek good though too cuz you can just bootstrap with the relay and not add anymore. 

 I'm write directly to theforest over the relay.tools client. Just need a browser extension, to login.
