I understand this isn't supported. 
I've been trying to confangle this myself but not having much luck, feels like I'm missing some critical info on how to configure `docker-compose.yml `and `nginx.conf`. I've tried a few iterations now but here's what I thought would be close. These are the only two files I've edited thus far, I'm using 0.16.2 for my 2nd front end so I can tell when I'm using it. I can view localhost:1236 fine but not localhost:1237 which gives me 502 bad gateway error, favicon still appears in tab though.
I'm thinking I need to open a separate port on lemmy to config another upstream entry in my nginx.conf? In prod the goal would be to have each frontend under a different subdomain for a research project I have in mind.

What is offensive is just a personal perspective so you’re gunna get mixed answers. Ultimately it will always come down to what the person meant by it and how the other person perceives it, by default that is a mixed bag of emotions and reactions.
I’ll note that I do something I call synonym panic where I get to a keyword in a sentence and I kind of blank, start struggling for words then start cycling through all the possible words I could use it and often land on some pretty odd sentences. Referring to the ‘past’ as the ‘back-timies’ as a prime example or more commonly just saying the ‘stuff’ or ‘things’ because I’m afraid I’m about to choose the wrong word.
