I have a feeling I saw this same post on a Grav-powered site, and would have responded from my own Grav site to the effect that it is not easy to get indieweb going with Grav, unless you are more adept than I am, but it is possible. Now, here you are on WordPress. So, not sure what is going on. But hey, each to their own.
And I will PESOS this comment back to my own site just to confuse matters further.
Well, up until a few days ago, this site *was* on Grav. I did manage to get basic outgoing webmentions working, but I had no way of having any reply show up on my site, and definitely no way of replying back to it. So thank you very much for your reply, but the only reason I can see it is because I converted the site to WordPress and set up all the IndieWeb plugins. As much as I like the *idea* of hacking away at PHP, IndieWeb is fairly complex if you don’t code for a living.
