Opt-in Creative Commons licencing plugin for WordPress?
Does anyone have a recommendation for an opt-in Creative Commons licencing plugin for WordPress. That is, one where the default state is not to CC licence something, but when some action is taken, an individual post or page can be so licenced.
As background: I have no desire to write, maintain, or even debug a WordPress plugin. I want to know if there is something for this use case that Just Works.
I want opt-in, because it is too hard to remember, or to train others, to find an opt-out box when posting, and thus end up CC licensing things that weren’t intended to be, or can’t be, released under such a licence.
Some options I’ve already looked into:
WP License reloaded: was pretty much exactly what I wanted but doesn’t seem to be actively maintained and is now failing (possibly because the site in question is now hosted on SSL, I’m not sure, see above about not being interested in debugging).
Creative Commons Configurator: seems to be the most actively maintained CC plugin, but seems to be opt-out, and even that was only introduced recently.
Creative Commons Generator: opt-out.
Easy CC License: perhaps what I want, although I’d rather do this with an options dialogue of some kind than a shortcode.
