Look, I know that there is a bit of book "acquiring" going on around this site. It is far too easy to ask for PDF's and eBooks in a virtual tabletop compared to sitting around the table in a Gamestore.
My worry is that at some point, either two things will happen:
1. The companies will stop making new books for us
2. The wrath of such companies will be put onto these Virtual Tabletops
So we need to stop announcing it and moderators need to be a bit harsher on people who do. I would hate to see a small company like Roll20 end up in worthless litigation.
BTW, not saying you can't, but have some tact. Don't ask on a public forum.
