Does anyone know of a way to get these? My current workflow involves Googling for the skimage mailing list, finding the right link (it's not the top hit), hunting down the right message, and then two clicks and a copy-paste to get the link.

Nabble provides them by default (much as GitHub does), and they are very useful, since mailing list messages are often quite shareable. I'd even advocate moving to Nabble if there's no way to do this.
