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.
On Sunday, I have an open to close shift 11am EST - 10pm EST. I will not be able to play on Sunday. Waiting till the weekend isn't the best idea, unless you want to aim for Saturday, which I work 5-8 as noted above.
