Player Add Notification
There should be a function to submit a player you are wanting to add that hasn't been registered in the system yet. Once he is added I should be notified directly by yahoo to have first chance of obtaining. I'm specifically referencing Hector Oliviera from the Dodgers. Currently I check every single day to see if he has been added yet with no real timeframe to understand once he is added.

How about announcing newly added players in the notes link on the league page(next to the league name).
When a player is added to the pool, they start off on waivers. That gives everyone in your league a fair shot at obtaining him.
