Re: Easy way to rename the wire (and all the others) ?
I’ve recently started doing this for the purpose of renaming a few of the predefined labels as well.
I use PoEdit and followed the instructions listed here:
https://codex.buddypress.org/how-to-guides/customizing-labels-messages-and-urls/
The “Labels and Messages” section is what you want to read up on.
Follow them explicitly and you should be good to go.
You’ll probably want to find a PoEdit tutorial on Google as well.
