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.
Also I realize I made a small mistake with the scheduling - for the following pairs, the games don't need to be done by the end of this week (since these are actually Round 2 games). You are still welcome to play your games if you like, the deadline for these pairs will just not be until Sunday, May 14th @ 11:59PM GMT-4 . Sorry for the confusion!
