Hi teachermom!
A lot of questions, let's look at them one by one.
UpgradesWhen upgrading your subscription, you will simply pay the difference, there are no additional charges. With regard to benefits of upgrading now rather than later, you will still receive the same products, course lessons etc. so you will not miss out on anything.
Also, will I be able to keep files I've downloaded from the forums? The free and "paid" content using my points once my 6-month subscription ends?Yep, and yup!
If I want to use the Semester 1 curriculum with my new baby (in a few months), and I purge, will I lose the days I've already covered with my older child??The Purge function in Little Reader doesn't work that way - it's used to purge unused files from your Media Library to save hard disk space, by trawling through all your Little Reader lessons and then determining which files are no longer in use by ANY lesson.
If you would like to set up multiple profiles, we would recommend installing Little Reader on a second computer, as the current versions of Little Reader do not allow for separate profiles on a single PC.
Hope that clears things up!
