create a central Lemmy redirection service
This is contrary to what the Fediverse is about. [[email protected]](/c/[email protected])
is already unique and an identifier to universally refer to that community. It automatically links to https://your-instance-URL/c/[email protected]
which makes absolute sense, because you have an account on your instance.
If you want to visit [[email protected]](/c/[email protected])
just open the link with your instance. Either by using the URL or by cop&pasting the URL into the search field, or by something like lemmy Link in your browser.
