How can users mark a job as no longer available

Hi,

When a job has been listed on the site by a member and they arrange for someone to complete the job, how do they then mark the job accordingly?

Ideally I would like it to be removed from the public list of jobs on the main jobs board but I cant see any way a user can do this,,, other than permanently deleting the job.

Can you please advise what options there are?

Many thanks
Chris
