Word on the street is that you may be interested in programming stuff again. So, here's a bunch of courses to get you started! These courses cost money, so hopefully they'll be a lot better than Codecademy :p
All you need to do is make an account on udemy.com, then click these links to redeem the course!
Aha! I'm glad you asked! If you didn't notice, this is caret.club/~paxton. That means this is your page! Your little home on the internet! You can put anything you make right here.
Another good question! First, get your website working locally by following the lessons above. Then, when you want to transfer files, use PuTTY.
Call me and we'll go through it :)
