Forum member boltyboy reported that TypePad fixed "Post as draft" issue:
"Yeah, that only took 6 months! As far as I can see both the post as draft AND the post and publish with delayed time (set in the Blogjet properties tab) are now working properly! YEAH! This has taken way too long, but it now makes Blogjet and Typepad totally in synch!"
Thanks, boltyboy. Thanks, TypePad!
