Poster is now available exclusively on the Mac App Store. There is still a 15-day demo available to download from this site, but it cannot be activated with a registration code and will not run after the demo period expires. Existing users have been transitioned to the Mac App Store version.
As my newest app, Poster was released a month or so before the Mac App Store went live. So few licenses have been sold through my site that it is not worth maintaining two versions of the app.
Also, unlike my other apps, Poster has never had educational or bulk discounts, and since the Mac App Store gained promo codes, I haven’t needed to worry about NFR licenses either. Now the Mac App Store is available worldwide, it’s my hope that making this transition will not inconvenience anyone.
