Hi Richard, Matthew has given you an excellent response, however I thought I would add my two bits as a third party. I work at a university in British Columbia, Canada and we are in the midst of a project using CBox. I also know of another development that I’ll probably have some peripheral involvement with.
I can tell you that it is an excellent framework for our use case. I can also tell you that the developers of CBox are well-known throughout the WordPress/Education community and have been very responsive and helpful during our development. CBox is most assuredly neither “dead” nor “junk”.
Matthew provides excellent advice about approaching the Buddypress community and broadening your search. He also provides excellent about enticing developers. One of the things that developers groove on the most is working with clients to analyze their project requirements and use cases to arrive at an approach and solution. Some outline or synopsis of your requirements and use cases is necessary to attracting a developer. There is plenty of advice on the internet about attracting developers.
As Matthew points out developers are in high demand and fairly discerning in their project and client choices. They look for clients who understanding the developer/client roles and demonstrate an understanding of the market and ecosystems that developers work in. It may seem like a reversal, but good developers look at projects and clients in the same way an HR manager looks at a pile of resumes. The challenge of someone in that stack is to provide enough definition and incentive for a developer to decide if it is a good fit.
Anyway, I’ll stop for now. I do want to reiterate that CBox is an excellent framework backed up an excellent team.
Good luck on your project.
