Do you want me to make something for that I'd happy to do it
EDIT: I made one:
gemini://casualtyhere.midnight.pub/Gemiads.gmi
I highly recommend
it is a directory of capsules all over the geminisphere. I hope that helps
gemini://discovery.geminiprotocol.com/
Here is generally a good place, since most of the readers are inclined to enjoy Gemini already, but also Mastodon, Lemmy. It would be nice if there were a centralized place, though. There is also GUS.
