Online registration for the Kirkwood IFSA comp (March 30th-April 2nd) and the Snowbird IFSA comp (Feb 2nd-5th) can be done at www.usfreeskiing.com.
According md9, Snowbird filled up pretty quick last year, so if you want in on it, you probably should do it soon. It's only $25 to pre-register a spot for each event, so its cheap.
