I have an account on one server, but often browser from 9 other servers.
Do you literally open 9 tabs for each instances? If that’s the case, that’s kinda weird. You don’t have to. That’s the whole point of Lemmy.
Link for a community in lemmy should be something like this: [Link Text](/c/[email protected]). If you click that in whatever instance you’re in, you should be able to access the community in that instance.
However, quite a lot of people just don’t care and copy/paste link for the community which is (understandable, but,) quite irritating. So after I read this post I just wrote this hacky Tampermonkey script to fix those links.
