For some reason, the hacked code I had in place to make Gravatars show up in Posts and Comments mysteriously broke over the weekend, so after a bit of troubleshooting (and an attempt to guesstimate the issue that turned into a neat feature that makes the author’s email address link embed into their name) I gave up and just found a new plugin – Gravatars. Works pretty slick – and has quite a few more options than the previous hack had.
