<\/p>\nTo add custom content to the "Write" admin pages (where you write posts, pages or links), WordPress 2.5 introduces a new function set: add_meta_box()<\/p>\n
<\/p>\n
Simple plugin example :<\/p>\n

If you want something compatible with both WordPress 2.3 and 2.5, you will need something like the following:<\/p>\n
