Just an idea for the wishlist.
I use one plug-in called post expirator.
What it does is that it removes any posts or pages at a given time (to be determined by the admin)
This made me think.
I would find it very useful if I had a possibility to create articles for my membership site, and make them available for a day or two days unprotected (giving the search engines a chance to index them.)
When the day has come to protect that post/page it would be nice of that could be achieved automagically.
Just my $0.02 (about € 0,015)
