Thanks. Jamroom was originally set up to help musicians distribute their music; it still does this, so is still strong on offering ways to distribute sound and video files. As a Jamroom user (developing the Research Cooperative network), I've contributed feedback for improvements in how it handles text, and the JR team have made (and continue to make) improvements.
However, it is not a purpose-built text publishing platform like those developed for open access journals. But.. pdf documents, blogs and so on can all be uploaded, tagged, indexed and so on. JR has a core system module and then many optional add on modules that work with it. If I had a team of developers, I could then modify the css templates to jazz up our network - but I don't. So my policy has been to customize as little as possible, so that updates and improvements made by JR can simply be accepted and used without any further work on my side (I am a full-time researcher with no training in computer coding).
If you can tell me what might be useful for you, then I can consider if it is easy enough for me to implement with the JR modules that I am currently using.
For example, I can give you the ability to make a separate profile for your project, and test that as a vehicle for the project.
