Limiting related posts by date

Hello,

I love the plugin! It works fantastically.

Just a quick query though, I’ve been looking through the settings in detail and I can’t see a way to limit the related posts by date range?

I hav posts from 2011 coming up which is no good. Is there a way to limit this to the last year as the old posts are no longer relevant.

Thanks, I look forward to hearing from you.

Melissa
