Since August, you could invite yourself to google's Gmail (which now provides 2658MB of space) if you just gave google your US mobile number.
Now, google has made it possible for those with an .edu e-mail address from an accredited U.S. institution to invite themselves.
We here at symplification love gmail, and think that everyone should be invited, so even if you don't qualify as above, e-mail
from the e-mail address you want an invitation to go to, and we'll try to invite you.
