Martin, unfortunately I will not be joining the project. My concern is that you are currently working on your own without the community collaboration that WikiTree relies and strives on, while also linking to and advertising your own non-WikiTree website. As it has already been mentioned previously, it no longer makes sense for the One Place Studies to be deemed a Project when:
None of the functions of a WikiTree Project apply to the OPS project. The "leaders" of the OPSs are the managers of the individual OPS free-space pages, and they do just fine on their own. There doesn't need to be a project overseeing them.
Your best course of action at this point would be to start a discussion in G2G about the future of the official project. If enough members would like to keep the official project active, you could enlist assistance from the Volunteer Coordinators, such as Eowyn Langholf, in getting the project back on track and running - retaining the official status and not having to start over again as you are doing now.
It may even turn out that the general consensus is to remove the official OPS from Active Projects, design a Help page for the general creation and setup of an OPS, then dole out the remaining aspects to the place projects who have more experience and can offer more assistance to their users than an OPS project could. You could offer to be involved in helping to setup this Help page, providing general assistance, etc.
