Good ones, will work on them in the next days!
About the two servers, I don't know - our crawler needs a few days to go through everything for the initial listing, so it might just not have gotten to them yet. But the best way is to use the form to suggest a community from each of these servers. which will introduce them to the catalog.
Do you mean in Catodon? We don't have a link because you can already search the Catalog's index through Search and Explore in Catodon! It's the button saying "More from the Fediverse" when the server's search results end. But as we add more search options to the site, it might make sense. I'll think about it when the initial suggestions and changes have settled.
