[EventCalendar] QUESTION: Filtering The Loop for Events by Event Date; not Posting Date

[firetree_ec3 at spamex.com]

I'm pretty sure this question must have been asked before, but I  
can't seem to find it. The default mailman interface doesn't seem to  
have a decent search functionality.

I want to display my events by EVENT date; not POSTING date.  
Currently, they all list by post date, which can be problematic, as  
people can list events far in advance, and I don't want December's  
events listed prior to July's events.

The event dates are in a separate table, so I have to play SQL games  
to get at them. WP has some API calls to let you play with the SQL,  
but I was wondering if I missed something in the EC3 docs that allows  
me to do this.

I see that there is a "ec3_filter_posts_orderby()" function that  
probably does this, but I don't seem to be invoking it, so I'm  
wondering if I'm doing something wrong. I see that I should probably  
have $ec3->order_by_start set, but I'm not exactly sure how I do that.

I'll keep reading away, and I'll figure it out eventually, but a  
quick pointer to the correct M for me to RTFM would be helpful.

Thanks!
