I sincerely hope you are correct Andy, she could well lose everything if she deletes stuff from her profile page.
I am under the impression that once you delete any replay from your profile page replays section any copy will fail too.
You can delete replays from your profile page but you have to do it from the ingame save replay dialog box. I may be wrong but Sweetie, please don't delete anything until this is cleared up.
I know you're very knowledgeable guy Andy so could you explain to me why it is that when you delete a replay from your profile page, if you have a copy of it in your blog, that one fails as well.
