Oof, the 'how to get started' section of that page makes all the classic mistakes.
- sends people to join-lemmy - no, send them to an instance. Don't make them choose.
- "just choose any instance" - uhh yeah we know what happens when they do that. *.ml happens.
- says which communities to join by using their https url. When people click that link they'll end up on a different instance to the one they signed up on.
In addition it recommends joining the communities BEFORE signing up. The order is wrong.
They could have said
- Go to https://piefed.social/auth/register. Do the whole onboarding process.
- Go to https://piefed.social/community/buyfromeu@feddit.org/subscribe
- Then go to https://piefed.social/community/buyeuropean@feddit.uk/subscribe
