Oh wow, Im going to click on the generate coins button while i do gpu mining :p
I always keep the pc on anyway, so i cant loose!
If you've got access to free power (work PC's or something of the like) it never hurts to just have a buncha CPU's mining. While statistically low, there is a small chance one will generate a 50 coin block (we're talking seriously low, but every little bit helps).
Insert some statement about wasting power/hurting the environment doing this here....
Insert another statement about someone needing to offer carbon offsets for bitcoins so my soul is clean.
