There is a little-known but awesome Pogoplug feature that lets you email attachments directly to your Pogoplug Cloud.
You can enable this feature by signing into your Pogoplug account, then going to Account Settings → Email Attachments and checking the box. Just include firstname.lastname@example.org among your recipients, and your attachments will automatically upload to your Pogoplug account.
If you’d rather upload your attachments elsewhere, you can change their destination to any of your Pogoplug devices or computers with Pogoplug PC installed. Additionally, you can specify a folder within your Cloud, device or Pogoplug-enabled computer to be the destination for your attached file.
To upload a file over email, simply attach the file you would like to upload and send it to email@example.com.
