Yes, you can share your work with someone who does not have a PebblePad account.  This can be done in one of two ways:

1. When you choose ''I want to... Share... with people'' you will have the option to add a non-PebblePad user.   You will just need their name and an email address.  You can then share with them in the normal way and they will receive an email with a link to the asset you have shared and a second email with a username and password to use to access the asset.

2. You can share any asset to the Web and receive a URL that you can then share with others.  Anyone who has the URL can click on it and view the particular asset that you have published.
