I would actually leave it as vaporware if I were you. If a homebrewer doesn't like seeing the term associated to his game, he should just finish it and release it.
This was kind of my thought exactly! Being in the vaporware section isn't really a bad thing, it just means there hasn't been an update in at least one year. I chose one year because I felt that if you hadn't heard anything at all from the programmer about a project in that time, it usually means that the title is on the back-burner or possibly abandoned.
As soon as a programmer posts a new update, it will go right back into the active section.
There are a couple of the list now that are approaching a year since the last update: MazeaM, Penguin Adventure, SeaQuest, etc...
Even DKA had an update in April from Eduardo!
