BuddyPress - How do we change the "Registering for this site is easy" text?

Hello!

There are many posts online about changing the default BuddyPress registration greeting: "Registering for this site is easy, just fill in the fields below and we’ll get a new account set up for you in no time."

Apparently, it used to make sense to do this in the BP language file, but the best I can tell is that the language file was dropped from the new version of BP, and many people with extensive language edits struggled with the change.

I have also read this thread https://premium.wpmudev.org/forums/topic/change-registration-text and tried the advice of modifying /buddypress/bp-themes/bp-default/registration/register.php to change the text, but that didn't work. (I made certain to clear my browser cache, and there is currently no caching enabled on our server).

I've tried the Find and Replace plugin, and the Quick Localization plugin.

Does anyone know a method for changing the registration greeting text?

Thanks for any help or insight!
