If you were previously working on a Learning log but hadn't yet sent it for review (shared it with your supervisor) and now it is attached to a previous review period you can bring this into your current review period.
To do this first click through into your All entries page:
On the all entries page you can filter to just show entries that haven't been shared:
Then click the button to bring it into the current review period:
If the entry had previously been sent for review or isn't a Learning log then you can use the Create a copy function from the entry page to create a new copy which will then be linked to your current review period.
