why can't I return a packet that is only half way done? How do I save what I have done so far so that I can return back to the packet the next day?
If you bring up a batch to work on and for some reason you have to leave before it is finished, don't worry. The batch will be there when you come back to FS and everything you have done will be there for you to continue on. At the top of each batch it will show you how many batches you can have open of that type at any one time. However many you have open, they will be there when you come back in, whenever it is.
Each batch does have an expiration date usually 10 days or so. If you don't complete the indexing/reviewing in that time it will go back for someone else to work on. Happy indexing/reviewing.
Margaret, it automatically saves when you click the back arrow in the program. Even if you just close the window like you're done with your computer, it will be saved and you can bring it up again on your main indexing page.
To expand on @Dave Morris6's expiration date: on your main indexing screen, you will see a due date by every batch. The due date can be anywhere between 4 and 10 days, depending on the project. I am currently working on New York Land Records. This has a due date of October 22. The date is midnight Greenwich Mean Time (GMT) on October 22. I live in Illinois, which is 5 hours behind GMT, so my batch will be due at 7:00 PM CT on October 21. You can use any world clock site (or just a handy-dandy search) to find a GMT converter.
