Also, I'm working on my postentry module, and generally, it goes well, except that I'm not sure of the format of the meta-data. For example, I tried to set current_mood and current_moodid, yet they were not reflected in my test posts. I'm using flat format, so I assumed that it was just current_mood=mood and so on, but it didn't work.
Any help would be appreciate. I realize that these are novice questions, but the docs are a bit unclear.
