Sylabus update (for group staff)

Hi

I’m working with php/mysql on a sylabus update application.

I need to add a group function on to the existing application, so it records who has done what section, though only one person actually logs in.

To take account of people possible leaving or arriving late I would have a

“group change” function, where people input thier name then select arrive/depart and add remove from present staff.

“present staff” function would add a 1/0 to each section according to staff present

then at the end an email will be sent to an admin for those who completed

whilst those who only did a few sections would have the information corrisoding to the ones they did send to their file.

Does this sound plasuable? Any simpler routes?
