That's a pretty rude comment to begin with. But to answer your question: I distribute my staff according to their preferences, their time and my priorities. And projects that are almost finished (few chapters left) have a higher priority. If you want Platinum Garden that badly, learn how to edit and help out.
If you disagree with my "good business practice", start a new scanlation group, take over Platinum Garden and do it yourself. :) Besides, there's a wide accepted policy between scanlators that projects which haven't been worked on for 600+ days can be taken over by another group. If another scanlation group would contact me on that matter, I would be more than willing to share our work and resources.
Those are the options. If I get a editor (cleaner and typesetter) interested in Platinum Garden, then I'll be more than happy to release the typeset chapters. Else it'll move up the priority list when other projects are finished.
