HelloFax is an interesting little tool, which works with Google Drive. If you still fax stuff to people (if you're wondering what 'fax' means, please ask someone rather older than you) then you might want to give this a go, as it will fax directly for you. Alternatively, and this is the thing that I find particularly interesting with it, is that you can automatically sign PDF forms with it. Upload a copy of your signature (or write it on the screen), save it and you're done. I've tried it and it works very easily and simply.
