I can’t believe it took me this long to figure out how to connect to my Bluehost account in FileZilla.
But yes, here are the easy instructions: https://box363.bluehost.com:2083/frontend/bluehost/ftp/accounts.html
Y’know, I think the only reason I haven’t done this sooner is because I had been in the very terrible habit of editing files directly in my bluehost or WP accounts. I’d never watched someone go through all the steps of working on files saved locally /before/ committing them to the site until very recently, when I sat in on a hands-on WordPress development workshop. I learned so many small but useful things in that class! It definitely deserves its own post at some point.
Anyway, lesson learned: not everyone uses git or subversion to commit files to their sites.
