why not add !offgrid@slrpnk.net to the sidebar?

I suggest adding !offgrid@slrpnk.net to the sidebar.

At the same time, consider removing the LemmyWorld reference. Giant centralised Cloudflare walled gardens are not exactly in line with fedi principles, and presumably a good portion of offgridders are somewhat anti-establishment and more inclined to favor decentralised venues.
