The actual community name hasn’t changed from !spaceporn@lemmy.fmhy.ml, right? I guess changing that would mean moving to a new community.
Even though I agree dropping the “porn” moniker from the community is a good way to separate from reddit. I think that changing the community name is not a good idea when the URL isn’t also changed. It’s just going to add unnecessary confusion. If there was a way to migrate the community to a new name, then the change would be good.
You can still find it if you search for the displayed name on lemmyverse.net (currently the site has a problem where it doesn’t show you all communities, hopefully they fix it soon because it was working before) but if you don’t remember the permament name it could be hard to do this link !spaceporn@lemmy.fmhy.ml . To make a link like that you have to write “!{ permament sub name}” and it will search for you ocmmunities with those names so you can click on them to make this link, like that:
Wouldn’t now be the perfect time to change communities in that case? The subscriber count is still low and people won’t really complain.
