Amend author in a posting
In order to populate my site, I have been posting a number of FREE ads on the site using my login ( admin ). After posting I then send the link to the prospective advertiser to show them what it looks like. If they want to make any changes I would like them to do it personally. How do I change the author on an AD posting and then create a new login and password for that advertiser without having to redo the posting?
