I've gone through several different plugins this week, trying to add "related posts" to my blog. None of them worked out of the box. I even installed side plugins (like 'regenerate thumbnails') to try and get them to work. Nothing did. Not to my satisfaction. After messing around and wasting too much precious time on the whole thing. I decided to try an app called LinkWithin. While doing a bloglift for "MamaLovesHerBargains", she asked about adding it. I'd seen it at work on lots of blog, but wasn't aware of the name. I'm grateful for the heads up!
OMG.....simple stupid! I LOVE THAT! no ads, no sign up!!! For blogger it's as simple as entering your URL and pasting a line of code in a gadget. For WordPress, it's simply downloading the plugin, and uploading it again on your blog. Worked immediately, nothing to set! Absolutely give it 5 thumbs up, and say........"don't waste your time with anything else"!
