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.
To my next UU Open opponent : I'm currently on a trip and I am really busy so I don't have the time to prepare for round 5 and I go back on Sunday afternoon, so if it's fine with you I would like to request an extension.
To my Round 3 opponent for the UU Open : I'll be on vacation during the upcoming week so I'll only be available on Saturday night or Sunday night (I'm GMT+2). If you can't play on these dates request an extension please.
