Since the original thread can no longer be updated in the OP because the user hasnt logged on in 6 months, and with new items gone missing, I think it is better that I create this new thread so we can keep all of the missing items in the OP. I copied and pasted most of the stuff posted here from the old thread I made this self moderated in order to delete posts that could harm the future value of a coin? and because the last one was self moderated.
