I recently got an email from Backupify, an online service that I use to backup some of my online services such as Gmail, about a very cool offer. Basically, I can invite 5 people with their email addresses to sign up for an account with Backupify. If all 5 people accept their invitation from me and sign up, my Backupify account gets upgraded for free to their highest service level which would cost me about $60 if I bought it. There is also a bonus for the people I send an invitation to as well. When they sign up with my invitation, their Backupify account gets upgraded to premium for free, worth $40.
I have 5 invitations to give away, so if you're interested, send me your email in a PM and I will send you the invitation, which, if you sign up for, your account will be upgraded to premium for free.
Here's the link to Backupify: http://www.backupify.com/
It's definitely a pretty cool service.
I'm sorry, but this giveaway is first come, first served. I will notify everyone when I have given away all of my invitations.
