1) You need to be able to install some software (it's a cloud storage program) on your computer (Mac or PC). It's worldwide, legitimate software and the file size is quite reasonable.
2) You need to go through the registration process (ie, sign up)
3) You need to have 4 different computer (PC or laptop or both )
You can then uninstall the software and stop using it, or you might find it useful.
I'll pay $2 for 4 installation on 4 different PC , to the people who successfully complete the two tasks above. It's possibly 5-mins work, but it might be 20-minutes maximum.
* You can only install the software once on one computer but if you have multiple computers and multiple email address you can get paid multiple times.
