If you find that you can access one of your modules, but that you can not access the content menu to add files, assessments, etc., nor can you edit any of the items in the content area or module menu, this may be because Edit Mode is turned off.
You can learn about using the Edit Mode in Blackboard here.
Another possibility for not being able to make changes in a module may be because you are not registered as an instructor on this module.
To ensure that you are correctly enrolled in an appropriate module, please follow the instructions here.
