So, I was just browsing around looking at MODs used for other forums (hey, I was bored, ok?

). I came across one that looks really useful and thought I'd post here about it.
Basically the mod lets a user save a post as a draft if they still need to add to it. Personally, there are a lot of times where I'll start a post, then realize I don't have the time to finish it up if it's going to be particularly in depth. This would basically add the post to the forum, but hide it from public view until the user "published" it to the forum, effectively making the official post. Until then, it wouldn't show up in active topics, searches, post counts, etc.
What do you all think of such a MOD? On a scale of 1 to 10, with 10 being the best, how useful would you think this MOD would be?
Depending on my free time in the next month or two, I may tackle this and see what I can come up with.<
