Indeed, Vkeris, Stanza is dead. Any day now, you'll be able to switch to Marvin, which is anything
but dead, see this
MobileRead section. Stanza served as the original inspiration for Marvin, so you will find virtually all Stanza features in Marvin, and much, much more. I'm saying that as a big-time Stanza fan who used it for years, until Amazon killed Stanza by purchasing it and halting its development over 2 years ago or so.
PS: We may be just hours away from Marvin's initial release on the iPhone. (It's been there for the iPad since last December.)
