You can administrate the attendances with the namelist of it. 

Place the dots to the right places next to the names of the members, and click 'Save'. The saved results can be seen by the members, and can be modified. 

If the majority of the members are in the same attendance status (for instance if the majority of them was present), then it is faster to put all of the members in the same status by clicking on the name of the status, and then mark the exceptions manually. 

It is not mandatory to fill in every member's attendance at one time, since attendance sheets can be modified later.  

You can give red (good) and black (bad) points to members, signaling their performance in class. 

Delete data

If you would like to delete the red/black dot, or the attendance information of a member, just click on the 'X' in the line of the member. 

Sorting the namelist 

The namelist of students can be organized according to name and ID, and ascending and descending order. To do this, click on 'ID' or 'Name'.
