I am a serial lurker here...
I hope some of you find these useful!
Photoshop and InDesign page presets
A generous helping of ISO page sizes along with LuLu ones for InDesign...
Use at your own risk etc!
Fonticate is downright fab!
Those are nifty...but is Photoshop's “required” folder a Windows thing?
If you're using a Mac you have to open the Photoshop/InDesign application package - you'll find the required and preset folders in there :)
