On the midwest.social front page there is a "Communities from our friends:" section that links to communities on other servers.

Rather than linking to those servers, I would recommend that you link to those communities via midwest.social to make it easier for people to join them. i.e.

https://midwest.social/c/science@beehaw.org instead of https://beehaw.org/c/science.

I've been seeing posts of people creating accounts on different Lemmy servers to join communities because they don't understand that they can join any community on any server.

Thanks!
