How to edit the 'Edit' link that appears at the bottom of all my posts

I am really struggling with one small issue.

I have enabled the TDO mini forms plugin. Everything is working fine, except for one thing. I can’t edit the link that appears at the bottom of each post that allows people to edit the posts. It currently reads ‘Edit’ but I want to change it to something else (e.g. ‘Please help and edit this article’)

I have looked everywhere and I just cannot find the code to change. I would really appreciate it if someone could post up the code that I need to change.

Thanks
