For the curious: hereโs how I moved my Bluesky account to @npmx.devโs npmx.social ๐ช๐บ See the thread for the remaining steps.
I used @baileytownsend.devโs PDS Moover. 1. Entered my Bluesky handle (one with the custom domainโI was using one at the time), the same email, and my Bluesky password (I know), then followed the default flow.
