Ok I looked into this more and this is how it behaves.

When you type up a blog and don't want to post it right away you hit the 'Save Draft' button. You will see the following view. Don't be alarmed, it did not actually post publicly!

This is actually just a preview of your post, not the actual posting of your blog. No error here, just no indication that it's not actually posted. Misleading, maybe, but that's what suggestions for improvement to vBulletin are for.

So to come back to it as if you were doing so later on, just click the 'Blogs' button and you'll see this list. Notice this wrench beside your blog title below.


This indicated that it's a draft and not visible to anyone other than yourself, and of course the admins and moderators.

This behaviour may be different from some of the other blogging sites than what you are used to, but it doesn't mean anything is broken, just a bit different.
