Looking for foreign Sheebit

[Rodney]

Nevermind a late answer, I'm glad there is one at all. So, here’s the information you’ve waited for:


 
You’re asking whether I’m interested in shinies? Any time. But I think in this case I’d rather have a that female jolly Minicorn with 5IV please, I’ll make good use of it.
 
Simply tell me when you can spare the time to come over to the Lobby, or to put your Pokemon on GTS for me to instant-trade the Sheebit.
PLEASE DON’T JUST THROW IT ON GTS, IT’LL GET SNIPED.

Alright, I'm ready to trade. How do I access this "Lobby" thingy? (sorry i'm still a newbie)
