Does anyone know of a 3.5 edition version of the venerable old module, "Keep on the Borderlands?"
I'm given to understand that Enworld has a conversion of pretty much all the classics. I'll also note that converting Keep on the Borderlands yourself is pretty easy as its filled with basic examples of core D&D monsters. Pretty much the straight descriptions of the monsters in the Monster Manual will do with a few weapon changes (or just change the weapons the humanoids in the module use to the ones in the Monster Manual).
