This website has pretty decent traffic as well as a reasonable level of engagement; there are certainly smaller websites, with less traffic, that already advertise for online casinos.
I wouldn't be surprised if the LCB Network would be willing to make an offer were Dan selling, but I would also say that it wouldn't be in Dan's best interest to sell, at this time, even if he might have a future interest in doing so.
Generally speaking, websites whose revenues are based entirely, or almost entirely, on advertising, sell for 3-5 years worth of advertising revenues. In the case of this site, there are no revenues because it hasn't advertised yet.
If we start with a base assumption that content will only be added to this site within the next year or two, then the best play would be to start advertising now with an eye towards eventually selling for that 3-5 years worth of revenues figure. As of right now, potential future revenues would be purely speculative, so if Dan sold, he would either be getting the lowest amount this website would sell for or tied with the lowest amount.
Worst case scenario, the website really doesn't do a whole lot in revenues over the advertising period, but even if it didn't, it certainly wouldn't be worth less than it is right now.
One thing that I think would give the LCB Network pause, at least, I assume, is that this forum is all but unmoderated. There would probably be more man hours tied up in cleaning up certain things (because you wouldn't want to flat out delete all content, as you want to keep as much extant content as possible) that the manpower to do so would likely cost more than what they'd actually be paying for the site.
If Dan ever does decide to sell, my opinion is that he should advertise for no less than a year first. It wouldn't take anything away from value and could only add to it. Based on what little I know about online casino advertising structures, depending on if Dan wanted anything by way of guaranteed income (preferably not), in theory, it might only take one player to result in advertising revenues greater than the site would sell for right now.
I also can't really entertain any questions on the business side of things as the above pretty much reflects everything I actually know about it.
