Hi physicsnewby,
I was slightly active on TP.SE and some of my SE posts are imported into the Q&A section. The rep of any meta posts is now set to zero for the public beta as discussed.
Are you active on SE? If so you maybe have on-topic posts for PhysicsOverflow that can be imported too? You can suggest them here
