@danyork I enabled mine but had to get the web host involved to get it to work on shared hosting.
FAQs were sparse a few months ago and I didn't really understand that all I was doing at the time was having my posts show up here. I couldn't interact as my blog (just learned about Friends plugin last week though).
Comments are off on my blog because spam isn't worth it so adding the ActivityPub plugin didn't make any sense to me.
Checking now, my follow to my own blog is still "Pending".
