The CFF has posted new selection criteria for CSCs and Senior Nationals. They appear to have opened up all CSC events to any fencer already in the respective cadet/junior/senior rankings. They explicitly state that one of their goals is to improve attendance especially among developing fencers, so that is a positive development. (Senior nationals still has the top-64 requirement, however.)

The document states that these criteria must be met 6 weeks before the start of the event. Today happens to be exactly 6 weeks before the January CSC in Richmond, so it isn't immediately clear whether these new rules will apply to that CSC, or to subsequent CSCs. Hopefully we'll get some clarification soon.
