Someone just notified me that a new free online space provider has launched, called Copy. If you know Dropbox: it's pretty much similar to that for as far as I can see now, only here you get a starting 15GB for free (instead of 2? at Dropbox). They now have a temporary? launch action: for each person you redirect to Copy that then registers himself, both you and the one registering get 5GB of extra space.
So therefore my idea: if anyone is interested in registering, register, then copy your share-link to this thread, and the next person who is interested uses that link to register and then posts his own share link here. That way everyone will get +10GB extra: one for joining, and one for the referral of the next person.
I'll start. If you're interested, join can join using my referral link.
Have fun! :)
