What does 'C' and 'N' on the mobile app of steamgifts mean?

Contribution/Not Enough I think.

Cinnamon/Nutmeg obviously.

never seen N :D

Canon and Nikon.

To be honest, my first thoughts were a 4-letter word and a racial slur... :p

Cheese Noodles

There's an SG app?

C - Contributor. N - Not enough.

It's actually C = contributor, but it isn't specified whether you meet the required value. "N" stands for "new giveaway".

This is true.

That's the crappy app. Use the other one. No forum on the good one, just use your mobile browser for it.

its the type of filling. caramel and nutria
