Hi again! How can I change the template to modify the text on the pop-up registration form?

I had previously made minor modifications to the buddypress registration form layout by adding a buddypress->members->register.php file in my theme folder. Unfortunately that doesn’t seem to be affecting the popup form. It’s not a huge deal, but I was curious to figure out which template your popup DOES use. I found panel-registration.php but changing that also seems not to have any effect. So now I’m curious… what would I have to modify to (for example) get the popup to say “Create a Free Account!” instead, and add a space between the field name and the “(required)” label?

I’m obviously missing something because I tried changing pretty much everything I could think of to no effect.

Thanks for any pointers!
