This is a highly-configurable job-tracking system that allows users to submit jobs and track them as they are completed.
To begin, just click one of the links on the left-hand sidebar. Look for a great deal of context-sensitive help. Most links have tooltips associated with them. On screens where you are expected to enter data, the labels usually have help popups associated with them.
If you're feeling timid, just remember this: clicking links is 100% safe. It's only buttons you must worry about. So feel free to browse around all you like before you dare to click a button.
