Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
This sunday I am not really free... only in range 1.30-3pm +1. On saturday I am pretty free, in range 2-4pm my time and also after 9pm +1 until 11.59 pm+1... so I prefer sat if possible.
