Nah, he said "do not represent 1/10000 of total customers" so the number could be higher or lower, but not equal to 1/10000.
Effectively it most likely doesn't mean what he thinks it means.
However, logic dictates that the sales had started at zero and began climbing so even the unlikely condition had been true at one point. Correct would have been:
"so the small portion of merely forum members may or may not represent 1/10000th of those that bought the game"
(I still don't know what a merely forum member is but that's another story)
Madness? THIS IS MAAAATH! =P
Not necessarily! It's quite possible, and in fact I suspect it's true, that the fraction of forum members/total customers (copies sold) has never actually been 1/10000 or anywhere close to it for that matter. For the sake of clarity, I'm going to define "forum members" as people who have posted on the Elemental section of Stardock's forums - we can't simply count all registered members since Stardock forums share registration, i.e. there are registered members of the Demigod forums that could just as easily post here, but never have, which is why I limit it to those that have actually posted here.
Now, correct me if I'm wrong as I wasn't around in the very beginning, but I suspect the Elemental forums existed and received their first post before preorders were possible (if nothing else they had to post to announce that preorders were available, right?). So when the first post was made we had 1 "forum member" over 0 sales, which is a fraction we obviously can't calculate. Now when the first copy was preordered, we had some number n of forum members over our 1 total customer, which is n/1 - who knows exactly how much n was at that point, but the result is greater than 1 at any rate and nowhere close to 1/10000. As more and more copies are sold, and not all of them sold to forum members, the total customers has probably surpassed the number of forum members, reducing the fraction below 1. This fraction may be gradually approaching 1/10000, but as we have more than 8 forum members, we can be certain it hasn't gotten there yet. It may get there someday, if Stardock sees massive sales to those who don't post on the forums, but certainly not yet.
And this concludes my proof that Femme Fatal is literally correct, the number of forum members does not represent 1/10000 of total customers. In fact we never have represented 1/10000 customers, or anything close to it, not in the history of these forums or Elemental.
[On second thought, it's remotely possible to achieve the 1/10000 fraction early in the forum's life; if, just as an example, the hypothetical first post announcing preorder availability was immediately followed by 10,000 preorders before the second post could be made. But this is unlikely, and anyway Femme Fatal's post probably means that we do not currently represent 1/10000 total customers, which is certainly true regardless of any extreme situations that may have existed in the past.]
As an aside, Sir Raven I support your quest for more "epic" in our battles, and I apologize with dubious sincerity for my deliberate, shameless, and not-entirely-serious thread derailing. I'll just consider this a needlessly-wordy 'bump' to assuage my conscience.
