I posted a job on the c5.org job board, then noticed some wording I'd like to change. I hit the "edit" button visible to such a job posting's author, and made my changes. When I click the "X" box to close that window, my changes are not shown. When I click the unexplained "green envelope with an arrow" icon at the bottom of that job posting edit window, a graphical "twirling dot" icon spins and spins, but my changes are apparently never changed. Does the job edit function really work? What am I doing wrong?
