Today I received a tweet linking to the following message:
"Refer 3 friends to Projects and get a year's subscription to Nature free! We're giving away a 1 year subscription to the #1 science journal, Nature, when you refer 3 friends to Projects.
You'll get unrestricted online access to Nature, 51 issues in print and access via the Nature Journals app for iPad, all worth a whopping $199.
Your friends will also each get a 30 day subscription to Nature.
To be eligible, you and your 3 friends need only install a free trial of Projects.
So go on, download Projects and start spreading the word now."
NOTE 1: I haven't labelled this a "freebie" since you have to do a bit of work (refer 3 friends and you and they must download the free trial).
NOTE 2: I haven't had time to complete the process yet, so I can't say the offer works!
NOTE 3: These guys are based in UK, so I hope they will mail to Oz.
