I'm still convinced that making a forum sticky thread that everyone can check at his own pace, it's best than sending emails to every purchaser.
Sending emails nowadays has become less and less reliable: a lot of the emails we sent to original purchasers of Honolulu to notify them of their discount option, have been lost for several reasons, from user changing email after the purchase, users that purchased PHNL with a fake email (or, simply mis-typed), users with their mailbox full, and aggressive anti-spam filters either on the user's end or the user's ISP end, that simply killed the email so, we had to re-send lots of emails to new address, and probably some users WILL miss their discount because of having to rely on emails.
And, a forum announcement it's also beneficial for potential purchasers (that will not get any email) that simply check the forum and want to know about potential problems and if and when they are solved.
And, we are also considering a "global FSDT updater", a software utility that will check all your installed FSDT products, notify you of updates and install them automatically, downloading only the single updated files, saving a lot of time/bandwidth/headaches to anyone so, when we'll have this ready, it should fit everybody's needs.
