A while back I built mention.tech which is a webmention sending tool with a couple of differences - you can set it as your webmention endpoint, and it will pass through webmentions, but it will also cache the mentions itself, in case the linked URL doesn't have an endpoint.What it didn't have was a way to look for all outbound mentions and send them for a post, so I added that tonight. It may need to work more carefully wiht h-feeds, but with an h-entry it should be OK.Try it out at mention.tech/mentionall
