Five unused pins and one resistor

Hi, everyone!

I've made an electronic control for a washing machine, using a PIC16F876A.
The PIC has five unused pins on portC, and I wouldn't like to leave them unconnected. Can I tie them all to GND using a single resistor or should I use one resistor for each pin?

Thanks!

Long time debate here ;)

My own opinion, configure them as input and tie them directly to GND. If in your program you're sure you don't affect their TRIS and logic level, this shouldn't cause you any grief.

Case you want to play safe, use one resistor by i/o and tie them to GND or Vcc.

Just set them as an output ! and you will not need a resistor(S)

And...leave them unattached to B+ or ground.

Thanks for the replies, guys.
The pins are already set as outputs, so I think I'll leave them that way.
