Hey Alishia Marie, Sorry about that.

for updating your email, I can do it for you, feel free to email dan@podyssey.fm (you can't do it on the app yet)

for sending messaging to other users, do you mean a private message? you can comment on their recommendations but you cannot send another user a private message atm.

I personally do want this feature as well, I've wanted to send DMs to my friends with specific podcast recommendations. We will eventually add this feature, just want to build it properly or else one bad user could easily spam all users.
