(Seriously. I don't have enough Philly-specific content to maintain a presence on jawns.club but I'd like to have its local feed as a column in my client here. And I pop in to my forwarded account on tabletop.social now and then just to see what doesn't make it to dice.camp. Why should I have to do this?)
If you use android and fedilab as a masto client, you can do this by selecting an account that you already follow from that instance, click their icon and than select the 3dots in the upper right, follow instance. It's now a tab in addition to home federated etc.
