I've no doubt it easy, but I can't seem to get any info about a post when I'm inside a plugin. For example I want the language and author for rendering, but they seem to be hiding from me. The way I've been approaching the issue is to randomly type in strings of stuff until php can deal with it, then see if it makes the author pop out. Not very effective so far... I'll keep poking around and post here if I happen to stumble across the obvious (and hope that someone smart comes along and just blurts it out for me).
EDIT: also the post date, and maybe the initial creation date. I'm trying to make the creative commons plugin work in the phoenix world. To stumble my way through it I use a lot of "pre print_r whatever /pre" and can't seem to find anything other than the current version of "this", which happens to be the licensing info.
