I'm afraid I'm struggling to understand what is for sale here, considering that this website doesn't appear to generate any income.
Currently, as far as I can make out, the hosting of the forum, and day-to-day running and maintenance are carried out and funded by the Negyesi brothers. They presumably have control of the database which contains the entire content of the forum. What else is there, other than the domain name "autopuzzles.com", which it would seem is only rented for a modest annual fee by Charles Oncina (Ultra)?
So if the site is sold, to an individual or a consortium, who decides what it is worth, and who benefits from the sale?
I'm probably missing something, but some clarification would be more than welcome.
