This just showed up on my Facebook feed and I wanted to share.
"June 15 is Free RPG Day and Chris Pramas's birthday! At midnight PST you can download the Mutants & Masterminds Hero's Handbook and more for free for 24 hours. Head over to www.greenronin.com to download this free M&M bundle on June 15! It'll be available for exactly 24 hours!"
I already have a print copy, but a free pdf would be nice too. Also, there will be other pdf's involved.
