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.
Later the better preferably, but as long as it’s after like 8pm +1 preferably would be fine ( can try and make something earlier work if needed though)
(Got entire day Saturday too if you ended up finding some time then instead and that’s more convenient)
