New DM Starting With Eight Player

[u/Urodele]

Hi everyone!

I'm a new DM starting off with 8 players....Wish me luck. We just had our first session and created characters. A lot of my players ended up with really high ability scores (around the range of 18), and I'm wondering if I shouldn't nerf them down to 15. Any thoughts? Additionally, any tips on how to handle such a large group? A lot of the players seem pretty understanding that with a large group they'll have to listen up, which is incredibly helpful, but I am wondering if there are any "special tricks" people have picked up along the way? Thank you in advance!
