Hi there,
Yes, QACMS has been in beta2 for almost a year.
The main reason is I been a bit busy trying to get my Master Degree. I would love to get people involved in this project, every contribution is always walcomed. The thing is that QACMS is almost unknown in the CakePHP world, and my skills as "Community Manager" are not pretty good as you can see.
However, despite of QACMS still in beta2, its API is pretty much stable by now, I mean no more big changed are expected for the next release. So current efforts are focused in testing, bug finding and creating a good QuickBook. We should do some serious testing coverage before releasing a stable version.
Summarizing. I been always open to contributions from the community, and would love to see more people involved in this project.
So if you're willing to help, it is as easy as forking the repo, or testing and reporting bugs found, or translating to other languages, etc.
PS: I'll create a "Contributing" section in the book.
Best regards!
