Well, I should have mentioned this before, but since October 2025 I was thinking about making my own OSCAR server as I really love classic AIM (mostly because of how simple it was on design) and for people using retro computers out there, but because there isn't a way to people to signup except the server owner using API commands through cURL (just as how mentioned in that video), I would have had to create a web frontend for the API for managing accounts, and honestly I never felt like doing it and I ended up scrapping that idea.
I nowadays host my own XMPP server for myself, I wonder if there's a way to implement a "bridge" between OSCAR and XMPP.
