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)

Deux des dix disques de la figure ont été noircis. Noircissez d’autres disques de façon que l’on ait toujours 1 ou 3 disques noirs sur chacun des 8 alignements tracés.

Two of the ten discs in the figure have been blackened. Blacken additional discs so that there are always either 1 or 3 black discs on each of the 8 lines drawn.
