[nabs-l] EDMODO AND downloading files onto a usb stick

[vejas]

Hi,
For school, I am using a sight called edmodo.  I'm not sure if 
any of you have heard about it or had experienced it before.  I 
needed to get a couple of files, so I inserted my USB stick and 
found the save button for the file I want.  After this, how do I 
get it onto the USB stick?
Also, I had one more question.  Have any of you who used edmodo 
ever had any accessibility problems, or is it completely 
accessible on the computer?
Thanks for your time.
