@jayeless That's interesting, and you're likely correct about the subscribing to see in search. I'll have to test it out (see if some of those communities show up now). Thanks for the thoughts on that!
I was a little worried that it might be too complex to have included all that other info - it was mostly trial and error that led me to it. So hopefully someone can get some use out of it. I keep hearing "Lemmy is so hard to use!" - and while it has its quirks, if you're determined, you can sort it out!
