Twitter can be useful. No, really. Install TweetMyPC and you’ll be able to lock, shut down or reboot your PC, download a file, send a file on your PC to a Gmail address and more just by tweeting.
First, create a Twitter account. Turn off public access to this so that people can’t see what you’re doing (click ‘Settings | Account’ and then check the ‘Protect my tweets’ box). Don’t follow anyone on this account.
Next, download TweetMyPC, enter your log-in details and click ‘Save And Close’. To see if it works, type a tweet like Screenshot. All being well, TweetMyPC will take a screenshot of your PC, post it online and send a link to your Gmail address.
