What permissions are needed to add/edit work items in TFS

I would like to grant my Q/A tea开发者_JS百科m permissions to create an edit bugs in TFS. I could just throw them into the Contributors group, but I would rather create a Q/A group and assign it permissions specific to creating work items. What permissions do I need to grant them. (TFS 2008)

It's actually going to be found under Area security. Within VS 2008:

1. In Team Explorer, click on the appropriate team project that you want to check/change
2. Choose the Team-->Team Project Settings-->Areas and Iterations menu.
3. choose the appropriate area. If you don't have any defined, or you want it to apply to all of them, choose the "Area" node.
4. Click on the Security... button.
5. The permissions to edit work items is set here: Edit work items in this node
