This hack allows users, via the Profile Editor, to have the option to attach their signature to their previous posts.

By design, phpBB only attaches your signature to future posts when you select the 'Yes' for " Always attach my signature: " . If you had not been attaching a signature to your posts before this edit, your prior posts would still remain without your signature.

This hack allows the option of selecting a checkbox to the option " Attach my signature to my prior posts: ". If the user selects the checkbox then all his/her prior posts will have their signature attached as well.
