About RetroFed
RetroFed

Welcome to the nostalgia-filled piefed instance of yesteryear.

Open Registration with Application questionnaire.

If you have a question or comment you can post in !meta@retrofed.com or message @DosDude@retrofed.com or @Die4Ever@retrofed.com

In case of downtime and/or emergency, we will post updates on @DosDude@mastodon.social

Some rules we try to uphold:

  • Be civil. Bigotry is not welcome. This includes (but is not limited to): transphobia, queerphobia, racism, ageism and ableism. We do not promote hate.
  • Communities need to be Retro or Retro-adjacent.
  • Please don't upload pornographic content. (use an external image host for that)

  • Show that cosθ=(u⋅v)/(|u||v|) for 2D vectors u and v.

(it is quite hard to come up with these challenges, so if you got any ideas, please post them)
