I am trying to find a community I created on lemmy.tf but nothing shows up. I created it yesterday night. Community is called guineapigs@lemmy.tf
Could it be that lemmy.tf and lemmy.nz are not federated? Does it take time for a new community to populate to the different instances search.
Ah you need to click the magnifying glass icon in the top right. That should take you to https://lemmy.nz/search which is different from the community tab search, that search box there is more like a filter.
Try the steps above again and see if you have more success.
Thanks now I can see the instance showing up.
