Over the Cliff I Go

Thank you to everyone who took the time to comment on last week's IWSG: Path or Cliff? post, where I dithered about which writing project to work on next. As you can see from the title of this post, I went over the cliff and went with the "Ugly Horror Manuscript" now known as UHM….

I greatly appreciated all your thoughts, advice and encouragement, and I feel better, more ready, to aid my protagonists in their fight for survival and to grapple with my nasty protagonist and her cohorts. 

I do have two questions/issues/problems to pose to all of you wise ones out there:

1) Is it weird that I don't have an ending in mind? I usually do, and it's kind of freaking me out that I don't this time. I have scenes that happen toward the end but that's it. Do you usually know your ending before you write? Or do you discover it as you go? 

2) I recently downloaded Scrivener, and I'm looking forward to playing around with it and maybe using it for UHM. Do any of you use Scrivener? Any suggestions for how to make the most of it? Would it be better to use it for a fresh, new ms instead of one that's already got a few versions written plus lots of notes and scrawls that would have to be entered into Scrivener?
