In a perfect world, PT Games, that would definitely be the best way. But don't we forever see thread instigators doing that, only for everyone who wants a copy to post their email address?
An example, DSC specifically said PM me and I'll send my phone number in this thread:
"Range of ca . . . new sellers" His thread was initiated in June and someone posted asking for a list yesterday - the list of people doing so is 6 pages long so far.
Someone else started a thread being even more specific about how to get more info, and the next few posts were specific questions about the offer. These were a couple of Koreans, so perhaps we could make excuses for their English (I'd be more inclined to suspect arrogance when they write so perfectly, but there we go). Everyone else just followed on instead of following the instruction of where to go for registering interest.
So, if there's an advertising place where it is impossible to reply, these illiterates would be forced to learn to read and help me save time by not having to read their superfluous posts.
