Ah, it's definitely fine to ask for battles or trades in the Ghost thread! However, there probably isn't much of a guarantee that someone in that thread would be interested in looking for a battle/trade, so it might be significantly easier to search for those in their respective sections. ^^
Same here! I'm absolutely awful at starting conversations. =(
Ah, I had no idea Mega Lopunny wasn't in Sun & Moon yet. I thought all of the Mega Stones were already there, but apparently not heheh. Oh yeah, and the game I was playing is called The Legend of Zelda: Breath of the Wild!
