Thanks for the review! Yeah, the upvote part was something new I'm working on, and funny thing is I even deleted the folder to not have it included in the PR, but then I undid the delete before the last commit :P instead of undoing it only after I did the commit. I try to remove some large commented areas before committing, but it's cumbersome to do and I forget. The server.js is something I need to finalize instead of leaving the large commented code in there, indeed.
