supports any wordpress version starting with 1.5 up to latest 2.3.3 version
Maybe not that one!
Would anyone be interested in a free service to do this?
I'm working on something at the moment along these lines and while I'd rather not sell it or give out the (undoubtedly buggy) code I've been spending ages on (it's not hard, I'm just slow!) just yet, I could host it (if you promise not to click on the ads!)
It's part of another project really, but not much work to get it online if anyone wanted to use it. It basically just creates wp format xml files to import with posts future dated (an idea borrowed from Seocracy's Datapresser). If anyone is interested let me know how you would prefer to enter your content and I'll get it sorted.
Alternatively this might suit you - bit of copying and pasting, but easier than manually entering posts:
1. From a WP blog (with at least one post) go to manage - export, save the file
2. look at file and work out what goes where - kinda obvious, but think i had probs with the tags, or maybe it was the categories.. and can't seem to get it to change the title and tagline, but that's not a big problem
3. Copy and paste your content into the xml file
5. Set the dates for when you want to post
4. Go to new blog - manage - import - wordpress
