No kbin.melroy.org subscribers that I know of. I don't know where I'd check if I could.
Another Mbin instance kbin.earth federates with us but doesn't have yesterday's post right this second. You can cause that post to federate by clicking here to search kbin.earth for that fedia.io URL. A few seconds after someone clicks that link, the post should appear on kbin.earth.
Thank you! A thread I just posted made it to Lemmy instances within 15 minutes. The thread that didn't federate two days ago has found its way there too. Jerry is the best instance admin and Fedia.io is worth paying money for.
