If that's the point I don't think that public messages should be given equal priority time wise, mainly because everyone can check a public message timestamp while a PM is, well, private. To me PMs are a way to setup private details, but since the selling thread was public I expect the offers to be public as well, or at least not to expect PMs to be treated like post replies.
furthermore, I already gave full verifiable proof of my ownership in the first post, so your initial request for direct verification by friedcat was somewhat redundant. I can't take your initial offer as an actual one.
After closing my deal with mechs, given the huge increase in price of AM shares, I'm going to close this thread and start a new one with an updated price.
