I love
I love it
Doesn’t even work right
Can’t exactly use the plugin when it doesn’t work. Avatar doesn’t show up no matter what I do, and the only suggestion from documentation is to go to an admin menu that doesn’t exist. Uninstalling.
still trying to figure it all out
this is the last time i’m writing this
