Question on posting material

Hi, quick question.
Is it ok to post (links to) PDF's and other materials we've made for AW or other games? For instance I may want to create a faceless playbook for all to use, is that cool?  Stuff like that.

You can link to your own work. There's no prob with links.

Don't publish others' work without their permission. Everyone who posts here keeps copyright of their own words; that someone's posted something here doesn't give anyone else the right to publish it elsewhere.

Also, there's already a Faceless Playbook.

But it's not for all to use!
