This task's deadline has been pushed into March because it's not worth doing until we have assessed whether we are to move to B2Evo 1.9.2. There's no point in doing a customization, then having to port it to a new system; best to undertake it on the new system if and when it's running.

In some blogs, we want outsider comments (e.g. the IMT blog, where users have posted bug reports). On others, we want to limit comments to logged-in users. This is not possible with B2Evo. There is a documented hack here showing how to limit all comments to logged-in users; in order to extend this to make it configurable per blog, we'd need to create a new boolean db field in the blogs table, add to the admin GUI a checkbox for turning it on and off, and extend the hack code to check for both login and/or this boolean before allowing a post. Not urgent, but very desirable.
