I've had YARRP for a few months now and have started to play around with some customisations. I can't believe I've not ustilised this plugin more thoroughly before now.
It's so very easy to use, and easy to customise to get the location and appearance you need for your Related Posts.
The support in the forum is magnificent and, until now, I've not needed to ask any questions, as everything that I've wanted to know has previously been asked and answered.
I'd give YARRP ten stars out of five if I could.
