And on last comment: in the original issue, I mentioned there will have to be some steps taken to actually get the content on the site. Did you want to take that work on? No big deal if not, and we can get someone else to do it.

Sorry man. Went through a breakup and relapsed hard on gaming. Almost 90 hours in the past 2 weeks logged onto CS2. Putting this onto my tasklist and will get to it this week.

Someone else can finish this, as I have no interest in finishing this. I moved on to working through FullStackOpen for the time being.
