Yes. Moodle courses, when created, have several blocks by default as well as a news forum. When you turn the editing on for your course, you will see arrows that allow you to move each individual block or delete individual blocks that you feel are unnecessary for your purposes. There are also additional blocks from a drop down menu that may be better suited to your course. (Any deleted blocks can be re-added at anytime from the block drop down menu which never disapears). You may also move the blocks around the page so that you have two columns instead of three. You can choose to present your course in weekly, topic or social format. Finally, you can add images and a variety of other tools to shape your Moodle course the way you want to.
1. Access Administration > Users > Permissions > Define roles.
2. Click the edit icon opposite the student role.
3. Change the moodle/role:unassignself capability from not set to allow.
4. Click the "Save changes" button at the bottom of the page.
Moodle sites have a little less flexibility than courses, but there are still quite a few changes that can be made to customize your site. Your Moodle administrator will be able to discuss these with you. One of the more important features is Categories and Subcategories, which will layer your site instead of simply displaying every single course on the site off the first page.
You can also display arbitrary blocks of text, HTML, images, audio or web links.
Ensure that administrators are not assigned another role in addition to their admin role.
Not easily. Each Moodle site has a number of "Roles" set up (e.g., Staff and Student). The site administrator can set up additional roles with any name and with appropriate permissions. Once available users can be assigned to these new roles within courses.
Additionally, you can change the names of existing Roles in a Course's settings page.
