No success. And the documentation on the site is lacking, or I was unable to locate it.
Looks like it has some nice features, but if administrators are the only ones that can use it, then it is of no use for 99.9% of a site's members.
What am I missing, and where can I find it?
I don't know how you managed to spend SEVERAL HOURS setting up a test project. The documentation is located at docs.projectfork.net. I also offer great forum support at forum.projectfork.net. In any case, Projectfork is clearly not for you or any other small-minded individual who is unable to locate the documentation or at least ask for help.
