There has been a steady trickle of new users here today, and in the past little while, mostly due to the bad decisions that reddit is currently making.
Anyways, welcome! Feel free to look around, and if you have any questions about anything lemmy related, feel free to ask!
Also, if you feel up to it, introduce yourself in the comments below!
I'm not really understanding how communities work across servers. I was able to create /c/Nintendo, as well as subscribe to /c/Nintendo from lemmy.world. I can comment in either, but when I go to the one from lemmy.world from lemmy.ca I can only see my comment and none of the other comments in that thread.
