I've got a blog that's about 15 months old with around 160 posts. Right now my permalink structure looks like this (example):
http://collegeinfogeek.com/2011/08/how-to-build-the-ultimate-hanging-loft-bed/
I'd like to change my structure so that I can custom-define all the links and not include the dates. For example, the link above would be changed to something like:
http://collegeinfogeek.com/hanging-loft-bed/
How would you guys recommend going about this change without getting hurt in the SEO department? I'm guessing I need a way to generate 301 redirects.
