Questions, Questions, Questions

So I wrote a story a looooooooooong time ago (it might have actually been like the second story I ever wrote on Mibba, like 5 or more years ago). I was glancing through my old stuff on the site and came across it, and couldn't help but laugh at my absolutely dreadful writing skills at that point in my life. I started reading it, and I'm totally in love with the storyline I'd come up with at the time, but not a big fan of my writing skill.

I want to rewrite the story, but I've never re-written a story on the site before so I'm not really sure how to go about it. I'm hoping a more experienced re-writer will come across this blog post and tell me what I should do. Should I delete the story altogether and start from scratch, or delete all of the chapters and keep the actual story page up so that the people who were subscribed to it before get notified that it is being updated? Not sure what the normal protocol is for this situation.

If someone could give me some feedback that would be fantastic!
