I definitely used it as a DNS server internally and a few of the other functions. I was totally bummed to see them strip effectively all useful functionality from it. :-/
The payment industry as a whole is in the stone age.. ignoring the antiquated technology behind it all there are still a ton of industry discussions about even allowing now-legal medical marijuana dispensaries and things like that to become customers. Given that it all goes back to Visa/MC/Banks I don't expect it to change much soon.
You'll be fine with either. Just pick a camera you can afford and focus on quality glass (lenses). I personally prefer the Canon system so my recommendation would either be a T7i (DSLR) or, if you can afford the upgrade, the EOS R (Mirrorless and my current primary).
Biggest con these days on mirrorless is they tend to run through a battery charge about twice as fast as a DSLR equivalent.
For materials.. as much as I've not been fond of youtube in the past for whatever reason I find it extremely valuable today. Peter McKinnon is pretty great or if you want to start with landscapes maybe check out Thomas Heaton.
Yeah, strangely you cannot appeal if you haven't yet made it through at least once. At least thats how it appears. We're having the same problem. There is basically no recourse if there is a communication problem and you just need to contact someone to resolve it.
