I’ve found that the best way to load a post or community is actually to just copy the remote link and search for it. Communities usually take about 30 seconds to load but if you sit in the search results page for a bit it’ll show up.

But you may want to make sure that your instance isn’t blocked, by going to [instanceurl]/instances

Aha sorry, yes you can comment to any thread so long as you can load the post on your end.

Yep!

Lemmings sounds perfect to me!
