Text is added to the ePortfolio via the rich text module, which features a text editor and multimedia capabilities. By default, any section or page without content will have the module selector already open. If there is content already on a page or section where you wish to add another module, you'll have to do the following.
Click "Add a Module"
Make sure "Rich Text" is selected
Click "Add This Module"
Add your text
Click on the "Save" button
Whether or not your work is ready to be published and seen by anyone else, you'll need to make sure to save your work regularly so it's not lost by accident.
