Can we add a Mini-Conference Event Type or the ability to filter evenys based on the number of judges needed?

My notifications are swamped with events that are too small to worth the travel. As a result I miss out on notifications that actually matter. If each event could include the number of judges it’s looking for in could be included as a another way to filter events. The Mini-Conferences tend to be where I run a foul of this the most.

Can you elaborate on what distinguishes a Mini-Conference from a Judge Conference?
