Do you know how to disable the ability to log time to parent tasks?

Or to tasks users are not assigned to?

[Madalyn_Destafney]

The ability to log time on a task is tied to the user's license and project access. 

Only thing I could think of that would not allow people to log time to a task is to change the specific task(s) permissions to View instead of the inherited contribute or manage access the people on the project likely have. You could do this in all of your template parent tasks, may be a pain if you have a ton, but should help prevent people to log time to it. Do a test first on one!
