Redmine

Hello,

I ran into following problem:

I have several public projects on my Redmine server. Any user can access this public projects without need to be a member of project. Now the question came up, how a user can subscribe on email notifications of a project, in which he is interested. He wants to know automatically, if anything becomes new in the project.

Is it possible for a user to subribe to a project anyhow? Or is it possible for a user to become member of a public project without any action from project manager?

Many Thanks

Richard
