Probably, but since I've never spent any time reading outside the HP section I really couldn't say. I'd certainly recommend that the title be renamed to something like; 'My Immortal - a Harry Potter fanfic MSTing' so they know what they're getting.
It's always better to spend some time getting to know a section before you start posting - that's the basic rule of all forums and groups I've ever seen as well - and when that doesn't happen... Well, it isn't pretty is it?
