Bridgy Registration

I have some functionality in the Bridgy app that allows someone to register for Bridgy for various services. I'm thinking of moving this functionality into the Indieweb plugin. All it is is a series of links that redirect you to the Bridgy site and redirect back when done.

That seems like Indieweb plugin territory.

Start by reviewing the existing Bridgy registration functionality and the Indieweb WordPress plugin structure. Confirm the available service links and redirect flow, then determine the plugin entry point and how registration should return users to Bridgy; done means the agreed registration links work end to end.
