To edit or delete existing content, log in and then bring up the page you wish to edit. Look on the page for an "edit" tab or an "edit" link in the right-hand red sidebar. Depending on your user permissions, you might see this on all pages or only on certain ones.

To edit a page, click on "edit," which will bring up a page with a form for changing the page. Here you can change the text and settings. Once you have the text and settings in a suitable form, click on the "Submit" button on the bottom of the form. Note that certain sites may be set up to require you to "Preview" the page before you can submit your changes.

If you wish to delete the page (and you have appropriate permissions), click on the "delete" button near the bottom of the form. You'll get a second chance to confirm that you wish to delete the page, or to change your mind!

Note: Because Drupal is very configurable, there may be additional ways of editing and managing content. Please ask your site administrator, or consult with another user for details.
