tmac and/or tanner, the fact is that at 12:28 PM Saturday, tmac made a post. At 6:05 PM, tanner made a post asking "why did I make this post." Then only 2 minutes later, tmac makes a post quoting tanner's 6:05 post.
The 6:05 post seems to imply that the person who posted as tmac earlier is the same person as tanner, then the 6:07 post seems like an attempt to cover this implication.
An hour later, tanner comes back on and asks tmac (presumably)"what's your email?" This looks like tanner/tmac is the same person and realized his mistake in posting so quickly after the original screw up, and so tried to cover his tracks a little more.
The exchange is entirely between tmac and tanner (unless someone in that otherwise inexplicable chain was trying to communicate with swamphawk).
This is all circumstantial, and might not hold up as legal proof (that tmac and tanner are one in the same). Then again, it might. The fact is, even if those who think they are the same are wrong, tmac and/or tanner are going to have to put out a believable explanation re: the above exchange, one that gives another reasonable possibility other than yes, they are the same person. Barring that, most any reasonable person is going to assume this rumor is indeed true.
