Hi Peter

Using the bulk action and first accessed and inputting after and before dates for first access provides info on when someone first accesses the system rather than when they are enrolled.

There is a report source Site Logs that can be used to record enrolments using the Advanced filter of Action contains enrol. There isn't a filter for date so this would need to be exported into a spreadsheet to filter by date, This provides a record for each course enrolled in so can be used to show site wide course enrolments.

Craig
