For cost tracking purposes I need to be able to track time on issues for a group of staff who assist in the resolution of issues, but who aren't going to be directly assigned to an issue (nor are they going to be users of Gemini).

To achieve this I added them as users, put them in a specific Global Group, and attempted to assign the minimum roles (through the security scheme) requried to have them appear in the drop down list of users on the time tab of the issue page.

I started with just the 'Log Time' role, which didn't work.  I added the 'View Project' role (which make sense for them to have anyway), but this still didn't work.  In the end I had to add the 'Assignable To Issues' role to have them appear in the list.

Is the 'Log Time' role meant to allow time to be logged for / by the user?

Is there some other role I should be adding to allow this to happen without allowing issues to be assigned to this group of users?
