Here is my eligius address verified with my username as asked. Photos with username and date are attached in the links above. I can also give ip access to one of the machines to serious buyers , changing over the mining pool.

Looks like the signature checks out to me, but I'd encourage any buyers to check for themselves too.22:36:38

However, I've got to say that one of these sellers is still a scammer but we haven't determined who yet, so proceed with extreme caution. The other user is claiming that he signed a message FOR YOU, when you asked him for personalised proof that he owned the machines.. this is getting multi-level weird now, but should be easily cleared up with another signed message - with more detail - from that account. Can you help?
