I think developers underestimate just how sorely needed this add-on is, ESPECIALLY for roleplaying communities. It's already a pain in the butt for people to have to register new characters by making extra email accounts (because you can't use the same email for multiple characters) but now there Is no easy way to switch between them other than logging in and out, back and forth. Kinda sad for roleplaying forums which end up shifting towards communities like JCINK (or similar) that have this kind of functionality built in and included with hosting.
Makes me wish I knew how to code.
