Did you know that with information you have stored in Google Drive you can share it directly from Google Drive? There are lots of advantages to sharing information this way. One is not having to attach it to an email. This means you don't have to worry about file size.
Another advantage is you can not only say WHO can access the file, but also how much access they have to the file(s) you're sharing. Start at drive.google.com (using your This email address is being protected from spambots. You need JavaScript enabled to view it. address to logon), then select the file you want to share. Once selected click on the sharing button (circled below):
You will then have the ability to type in the names of people you want to share the file(s) with. As you type names the system will lookup people who have a salvationarmy.org.nz account. BUT you can also add people who DON'T have a Salvation Army account.
WARNING: Think before sharing externally ... You probably have access to personal information that is sensitive and shouldn't be seen by others.
By clicking on the Can Edit button you get a dropdown of other permissions. Select what access you want them to have before clicking DONE. This will automatically fire an email off to the person (or people) you've shared with a link so they can get the file.
This is a much easier way to share information AND leaves you in control of the file(s). At anytime you can revoke someone access meaning they no longer get to look at your files. This is impossible to achieve if you have emailed a file to someone.
Oh and bonus tip, you can do this from your smartphone with the Google Drive app too!
