Question about the stacking of positive energy aura of Vivacious creatures.

[killem2]

Does the Positive Energy Aura of a Vivacious creature stack for someone if they standing within two or more Positive Energy Auras?

For Reference:
Positive Energy Aura (Su): Any living creature within 10 feet of a vivacious creature gains 1 hit point per round due to the aura of positive energy surrounding it. Creatures that exceed their full normal hit points from this effect need to make Fortitude saves as if in a positive-dominant environment. Creatures with immunity to positive energy effects, as well as other vivacious creatures, are not affected by this aura. If conscious, a vivacious creature can suppress this aura as a standard action, but the creature takes 1 point of Strength damage for each full minute that the aura is inactive. The aura always functions while the creature is unconscious.

I would say that they don't stack, as it's from the same ability with the same name.

[killem2]

I thought this at first as well, but there is no rule stating same abilities cant' stack. Also most abilities will state if something cannot stack, for example damage reduction or spell resistance.

There's the general rule about what stacks and what doesn't. Going from that, there's two ways of ruling this: one in the spirit of the game, and one to the letter.
First is "same source, so doesn't stack." Second is "It is not explicitly stated, so it's allowed."
As a DM, in this case, given the relative weakness of the effect, I'd allow them to stack.
