Why not? Some times I'd like to
update my post, but, it's still in "development".
What do you mean? A draft is a post or thread that hasn't been posted yet. But if you posted it, then it's not a draft anymore..it's just a plain post.
Ummm... I mean the ability to draft an already aded thread or post?
Hmm, ok I get you. But, if it's already a "published" post, then it's not really considered to be part of a "draft" anymore. That is the whole point of having drafts - for you to write down your ideas BEFORE you post them. If it's already posted, then the best I can tell you to do is, either copy and paste that into a new thread and save it as a draft then delete the old one. Or just edit it to your liking.
Ah, I see. I guess you're right.
