Please note that Mr. Pi's offer is extended to participants in that thread only. He wrote "Anyone from this topic . . . "
It's my opinion that if you didn't actually participate in that thread, you'll be "over staying your welcome" if you write for the free ammo.
If he gets too many requests for free ammo, he'll probably think twice before being so generous again.
Use your best judgement.
