Use Redmine Wiki, project independent

Question

I'm searching for the opportunity to use the existing wiki in Redmine project independent.

Why project independent?
I need it for general topics and plugins which are not part from a project.

Or exists a plugin which I can use for this?

Answer 1

People generally create a "General" project or something similar for the global stuff.

Everything in Redmine is part of a project. There are no global areas with user-acccessible data. This is by design, is leveraged by the permissions system and other areas and is not about to change.
