Can I get job postings by e-mail?

You can. After you run a search for jobs (a simple keyword search or an advanced search with several criteria) you'll see a link to "Save This Search." When you click that link you'll be asked to name the search so you can re-run it in the future and whether you'd like to receive e-mail alerts when new jobs matching your search criteria appear on the site. You have the option of choosing a daily, weekly or monthly notification.
