Oops. I think I've missed Free RPG Day.
Since I'm nowhere near a friendly local gaming store giving away D&D Encounter primers or something like that I shall merely post a link to the all the free downloads (from samples to whole products) on DriveThru RPG
Also, here's some items on Scribd which are totally legitimate because there are mine and I put them there (unlike about 80% of the RPG documents there, but hey)
General Link: Inked Adventures - A Collection of Floor Plans (Free)
The proper paid-for Inked Adventures thingamagig sections can be found here: http://bit.ly/IAstore :)
I find free stuff unnerving. It's never free ... it's a trick! ;)
