The front page is called the Dashboard and you can edit this to suit you. First you need to click the Customise this page button.
Once you have done this you will see new editing buttons that allow you to hide, dock, and customise each of the blocks on the page. Notice also that the Customise this page button now says Stop customising this page and you also have another button that says Reset page to default. This will set the page to the site default.
You can also add more blocks by accessing the Add Block function which is usually at the bottom and on the left of the page:
The elements you can add include elements such as: List of courses; Global Search; Html etc.
Once you have finished, select the Stop customising this page button on the top right hand side.
