It's a bulletin board designed to match teachers, administrators, support staff, etc. with schools. When you find a position you like, you can contact the school directly to apply. You can submit your resume, which will be available for schools to inspect. If a school wants to talk to you, they can contact you directly.
Schools can list job openings and search for potential candidates in the active resumes.
Nothing to look for jobs. Nothing to submit your resume. Nothing when you get a job. Payment can be made by check, approved purchase order, or online credit card transaction. You can delete the job listing, or you can change it to another job.
