Thanks for replying again rabbit. I haven't read the t's and c's as I haven't yet submitted a story (and obviously now, I wouldn't).

Personally, if an author wanted a story removed from a site I ran, I would do it regardless of policies and terms. Maybe it would take a while to get round to it, but I'd do it on principle. I don't think any site is doing an author any kind of favour by putting their stories up, with the possible exception of really weak stories.
