If a prone ally is on the opposite side of a creature than another standing ally, does the prone ally allow the standing ally to gain combat advantage?

Can the prone ally also gain combat advantage from flanking an enemy with a standing ally?

Flanking requires that the other person meet the following conditions:

  • Opposite sides (prone characters still occupy the same space as they would if they were standing).

  • Must be Able to Attack (prone characters can still attack).

As a DM I do NOT give my 3.5e players the prone flanking advantage unless they have something to help with the situation. Prone is very situational on how the DM describes it.

Welcome to the site! I wanted to point out that this question was tagged for D&D4, aiming your answer for a different version is liable to lead to downvotes. – Pat Ludwig Dec 29 '10 at 8:04
Thats ok I pointed out it was for 3.5e but DM can use them for 4.0 at their choice. – IrqJD Dec 29 '10 at 16:25
Alright then, I did have to follow through with the downvote. – Pat Ludwig Jan 13 '11 at 8:06
I'd imagine that "something to help with the situation" includes being armed and capable of a melee attack? Prone in 4th edition does not remove either of those two effects. – GWLlosa Jan 13 '11 at 19:47
