#contracting Votes for pictures weren't counted correctly, because get_current_user_id was returning 0, because I didn't load all the right parts of Wordpress, so the user wasn't loaded yet. Thus when one person voted for a picture it showed up for everyone else too.
#contracting Find root cause for major bug that's been haunting me for a week. Realize it was caused by an off-hand change I made that I thought "wouldn't affect anything"
