I haven’t hosted my own matrix server yet. is it safe to join an instance? I don’t really know how private that would be. the question is when I signup/login would I be giving out my IP? is the metadata private? sorry for asking this, I’m just a bit paranoid
Take a look at this link: https://matrix.org/clients-matrix/
It has a comparison of clients features at the bottom. Some of them allow multiple accounts. Not all clients support E2EE tho.
