G2G is a website where you can easily share files, which are at your Gmail, with each other. You register at the website with your Gmail login data and your Gmail account will be indexed. After that everyone can see your files (including support for only the files you want them to see) and download/email them without ever knowing your login data.
I’m sorry but G2G Share is now closed.
Google has let me know that this website is against their policy and I don’t want any problems with Google.
