On Elance I always chose to hide the title of the job from public display after it was completed. This is because I often included confidential information in the title - like the website the job was for - which I don't want in the public domain.
But now on Upwork all these titles of my previous Elance jobs are shown publicly. e.g. when I post a new job the names of the jobs are shown at the bottom of that page.
I have contacted support and they have said there is no way to edit or hide those titles.
My request is, if a job's title was marked as "hidden" on Elance, it should remain hidden on Upwork.
I understand your concern and have shared it with the team. On Upwork it's possible to make a job private and hide the job description. However, it's not possible to hide a title of a job. We are going to address this issue for client's who migrated from Elance.
Thank you for bringing it up.
