Hello, I'm working on a wiki and when I stumble over an old picture that is never used anymore, I add a "delete" template to the file page so that in the future, admins can delete it. This template is a simple box with one parameter where the user writes the reason for deletion. I can type "~" at the end of the parameter box to add a signature every time I post it, but I always forget and it would be really nice if the signature appeared automatically for each time the signature is posted. Is there any way to do this?

Here is the page of the template and if it's any more helpful, here is the full wikitext:

 This page is a candidate for deletion. Reason: 

If you disagree with its deletion, please explain why at Category talk:Candidates for deletion or improve the page and remove the  tag.

Remember to check what links here and [ the page history] before deleting.
