Anyone try using the Fantasy Channel on XM to fill league spots

I have three spots left in a new $250 points league I am trying to fill to get the league up and running. I dont want to wait to long to get it filled to be fair to the guys that have already signed up. In the event it cant get filled I want to give them enough time to find another league in 2019. Dont want to take this into March. I think this is the best platform for dynasty baseball. Thinking of calling in to give the site some cred. Anyone ever try it?
