The way Lemmy works right now is you search a community in your instance for it to then get shown, so you need to first discover that community from elsewhere. With that in mind, what are some growing communities that you discovered that could get some more love?
thanks for making these relative links, so they can work across instances, but… they don’t actually work on a given instance until that community is first accessed there through search.
eg, your dev community worked for me (here on lemmy.ml) because someone else here already accessed it, but your news one was 404 until after I searched for https://lemmy.pineapplemachine.com/c/news on lemmy.ml to make it learn about it.
despite the amazing work over the last years there is still lots more to be improved :)
(i just accepted an invitation to become an admin here to help the two main devs be able to spend more time developing and less time moderating…)
for now, if you want to promote your instances communities to users on other big instances like lemmy.ml, i recommend searching for each community URL on various instances (login is not required for this) to make it easier for newbies there to click your relative links and subscribe.
