Sim- Send in your roster changes by the deadline and post your starters for games 1 and 2. By doing so you are indicating that you're ready to sim.
Contract extensions- Since I am such a nice guy I will let teams who are ALREADY in negotiations with a player to continue that til the World Series is over (whenever that is.) That means if you havent begun negotiations at all or with a player, then you're out of luck. If for some reason there is a GM or two that was unable to get their extensions started, you need to PM me and I might consider it.
