For example, if I wanted to link this community, I could link https://lemmy.ml/c/asklemmy. However, that would not be cross-instance compatible; others would have to paste that into their instances search bar.
How can I avoid that?
I’ve seen a syntax like this but it doesn’t seem to work in the preview: !asklemmy@lemmy.ml
I mean, pasting that link into the search bar is exactly how you can subscribe to it from another instance. I don’t think there is another way.
It would be great if all instances would have an index of all communities on federated instances but it doesn’t right now, so you need to help it. :)
