The 2015 issue of the “One Page Dungeon Compendium” is up on DTRPG. I’ve posted the previous compendiums before, but you can find links to them on the same page at the 2015 issue. They’re “pay what you want”, and have some nice dungeons for one-shots, side treks, and ideas.

“All profits from the sale of this compendium go towards the next years prize fund.”
Cool!
