I've made some small updates to the system today:

Swim Sessions
When you view your swim sessions under "Setup, Swim Sessions", it now displays how many swimmers you have assigned to that session in brackets next to each one.

Attendance Reports
You can now pick a specific month to list the attendance records on your "Group ReportS" page. So if you wanted to see who attended for July, simply select "Jul" in the drop-down field for the month and click "Run Report".

This uses the current year only.

Exporting Data
I've added a new finance report to the data export page; Outstanding invoices 3 months or greater.

This way you can chase the late payers more easily.
