Hello! And thank you for hosting!
I'm still finding my way around and I've kind of figured out the remote subscribing thing...but there are some communities that I cannot see in the search despite knowing that they are there (if I visit the other instance directly). I've seen posts where people say to just do a search for that community and it will get indexed on your instance, but it doesn't seem to be working for me.
For example: /c/[email protected] is a valid community over on beehaw, but I can't subscribe to it by searching it here (or by going to the extended URL myself) and despite having tried several times to do the search, it just isn't indexing for me to be able to subscribe to it.
EDIT: I have now been able to get it added. Beehaw was probably just overwhelmed this morning. Thanks all for the help.
