I hope this is the right forum...
I have used MS WL Skydrive for a few years. I like the 25GB free on-line storage.
All you need(ed) to register was a Hotmail or Windows Live account.
HOWEVER, this freebie is now changing to only 7GB, and you will have to pay for any extra.
"Loyal users" can maintain the free 25GB if they act soon. I did, and it seems to have worked.
