I've been fiddling about with the Archive Shortcode lately and it's good. Saves a lot of time and heartache (and typos!).
Just one suggestion for the WordPress staff/developers to consider:
A shortcode option that gives post-by-post for a particular time period (for example, to specify a certain month) so that the end result would look like this:
September 20xx <-- this I would write
- [headline] <-- this lot generated by the shortcode
If WordPress could make this happen, I'd be supremely grateful.
