Hello Mark,
Thank you for your post in this link, for this link http://ww.wp.xz.cn/support/topic/show-only-authors-posts-in-admin-panel-instead-of-all-posts
This really helps to me, but one more thing if this is possible? I also want the administrator to view all of their posts, currently, when i paste the code you write in function posts_for_current_author, Administrator cannot view the post of the other authors, Hopefully admin wants to see all their posts. Thank you for the help Mark
