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.
7pm gmt is in the 2-5:30pm est time bracket that you listed o.o I'm not gonna be able to play the 9-11pm est time bracket because it's like 2-4am for me which is really too late for me, but the earlier time from 2-5:30 time bracket is manageable. Can you make those times on thursday? if not we'll just play sunday.
I've not played or built yet so thursday is genuinely a push for me, I've had no time and i've got an exam tomorrow then work straight after college so i'd have to build instead of revise tonight which i really don't want to do since i was busier than i thought yesterday :x Is it okay if we can play sunday? it'd give us both time to learn the meta :]
