@harald @LibrarianLisAnn I ended up not using Visual Studio, instead when I wanted to edit a file (I can't even remember what it was for), I used NoteTab.... but when trying to open a file to edit from FireFTP, it tries for Visual Studio first & that's why I installed it.
I haven't tried SMTP, that may be a question for Everleap.
As for email, through Everleap the address I have is now email@example.com so it's not bad. (firstname.lastname@example.org). I'll have to see more places in the game where the email is called for and test whether in-game emails work.
