Creating an ePortfolio is as simple as clicking a button.
Click the Account link.
Click the ePortfolios link to access all personal ePortfolios.
Click the Create an ePortfolio button.
Name your ePortfolio by typing in the ePortfolio Name field [1]. Decide if your ePortfolio will be public [2] (you can change this setting later) and then click on the Make ePortfolio button [3].
Once the ePortfolio is created, there are several options for creating content for your portfolio, including a wizard that will walk you through your creation, step by step [1].
