The same information as for the Principal Investigator of the proposed project is required for each Co-Investigator, except for the user identification giving access to the proposals in the working memory. When finished with a page, use the commit button, as usual, to commit the information to memory.
At the bottom of each Co-I details page there is a ``Delete Co-I Entry'' button to remove a Co-I from the list of authors again.
When finished, and after committing information to memory, use the navigation tool to go back up by one level to the proposal level (§ 5.3). There, either more Co-Is may be added, or users can proceed to the ``Add Observation'' option, to enter observation details.
