Hi Detrie, Assuming that you want to have internal and external workers in the same project, you will need to remove the outside vendor's access through the sharing dialog. The main idea here is setup the project as normal then remove the vendor's access to all areas except their task(s).
Select all the other tasks and manually remove their sharing access on the task tab of the project.
Do the same with issues and documents.
Note: The tricky part will be when you add new tasks, documents and issues after initial setup. Unless you change the project level access settings your outside vendor will get access to the new tasks and issues by default. Unfortunately, if you change the project defaults this will apply to both internal and external users so that your internal users will not see new tasks by default unless you manually grant them access (if you change the project access defaults). Also, I don't think you will be able to hide comments that are entered at the project level (unless you make use of the keep private feature and have companies setup properly). A more secure (and perhaps simpler) approach is to setup a separate projects. One project will be for internal workers and the second for your outside vendors and use cross-project predecessors where needed to manage dependencies between the two projects. There might be another solution, but I can't say without knowing more. Daniel Cooley Kenall
