Just stopping in real quick because I need to reply to my bard class since it's important for a quickly approaching Pathfinder game I'm running:

Zhdarkstar, Warforged were never part of the OGL, so I believe the thread you linked to could be doing copyright infringement. Regardless, Warforged were never made as part of Paizo's material.

They did introduce an Android race in the Inner Circle Sea setting if memory serves though, so you could re-do your archetype for that.
