What I ended up doing was creating one global corporate project. On it are 3 tasks: non-project activities (like meetings, calls, etc.), personal development (training, etc.), and research/discovery. Our project hours per day set under preferences is 6 (not 8). That means we have already accounted for the types of things that will be entered on this project. Because I do not want these project hours to be included in any resource management or capacity planning, I set up each task with 0 duration, 0 planned hours, and NO assignees. All users log hours to one of the 3 tasks. This way their supervisors can review for management purposes. Hours are logged, doesn't impact project planning...win/win. It took a little monitoring at first so users weren't logging things at the project level, but then it was smooth sailing. The only other habit to change was that their comments about what they did need to be entered "on" the time entry audit item, NOT on the task. Hope that helps.
