Guess his sales are down.
I kid, I kid.
Stick around. Come out and play with the rest of us. (outside the classifieds) We're mostly good people and would love to have you.
Unless you are communist. You aren't a communist are ya?
OP. Your question was answered. It won't do any good to have transfer paperwork done, it doesn't prove ownership. There is no "registration" in Indiana either. What you were asking for makes no sense. This was pointed out to you several times. People looked at your post history and saw the obvious, you are a seller. You hit the classifieds back in Feb of 2012 and haven't left. You have 6 posts outside of there since then, including this one and your "question" post. Of those 6 we can't really count 2 of them since they were directly related to your WTS posts. There was a 5 year block of time you didn't do anything at all on INGO. When you did return it was to sell more stuff in the classifieds. You show no interest in contributing to the forum, it's simply a place to hock your wares for free.
Taking all this into account, and reading your "question" post lead quite a few of us to think you are trying to figure a way out for a questionable sale, a possible way to CYA for a bad deal maybe. I don't know (or care) if that's the case or not, but it's a possibility based on what we can read about you. There aren't many here that are going to help you do something questionable. You did not get "attacked". At worst you got mildly hazed.
If your goal is to continue running a freelance business and you want accountability then check out gunbroker or armslist, insist on a bill of sale for each deal you do. You will have your proof of sale and a wider more appropriate audience.
INGO should not be home to unlicensed dealers, and that's what selling for profit without a license is. That's what is happening here, and with many others in the classifieds. There are better places to do that besides INGO.
