[Cip]

The code in the first post works excellent and it was the way I read I was supposed to do in order to post replies from a custom page (although some of the lines regarding visibility are redundant, I was unsure how I was supposed to make it skip moderation, but later on I use approve_post()). I looked at the documentation for the API and I couldn't find anything that seemed out of place.

I'm starting to think along the lines that $newpost['username'] should contain an array of information about the username, but that seems dumb.

All in all, I'm confused :-P
Thanks for taking your time though, it's greatly appreciated :-)
