Somewhere in the darkest corners of t'internet someone will have details of why things are called as they are. How interested are you in searching? :)

It did. Adding date data to a blog post creates the slug. Yay!

New Post: Will it? [bazbt3.10centuries.org]

Almost. The date is way off. Thanks for asking!

Actually yes, but it looks as though I'll need to create a posted date or a post slug. Fun! :)

No. One more go.

New Post: Again incompetence [bazbt3.10centuries.org]

Thanks. I'll have a go using the data returned (assuming I can interpret that.) :)

Ah, ok. What's my channel id please (or how do I find it)?

I'd hoped that my interpretation of the docs would be enough. :)

What data do I need to create a valid blog post?
