Is it possible to use the pcint pins PCINT16-23? They are also the analog input pins 8-15. Is there any example code that someone can point me to? Thanks in advance!
use them in what sense? digital pins?(yes) as pin-change-interrupts?(yes but tougher)
Yes, I'd like to use those pins as pin interrupt pins. The playground example shows us how to configure them if they are digital pins. If we want to use the analog pins on the Duemilanove, we just start numbering them 14, 15, 16, etc. I tried doing this with the Mega (54, 55, etc) but it didn't seem to work. Your help is most appreciated. Thanks!

Should work, here is extracted from the Arduino Core:
// For each analog input that can also be a digital pin, these
// define the numbers usable with pinMode(), digitalWrite(), etc
#define CORE_ADC0_PIN 54
#define CORE_ADC1_PIN 55
#define CORE_ADC2_PIN 56
#define CORE_ADC3_PIN 57
#define CORE_ADC4_PIN 58
#define CORE_ADC5_PIN 59
#define CORE_ADC6_PIN 60
#define CORE_ADC7_PIN 61
#define CORE_ADC8_PIN 62
#define CORE_ADC9_PIN 63
#define CORE_ADC10_PIN 64
#define CORE_ADC11_PIN 65
#define CORE_ADC12_PIN 66
#define CORE_ADC13_PIN 67
#define CORE_ADC14_PIN 68
#define CORE_ADC15_PIN 69
