Please be patient with me because english is not my first languge

Hello,

I just installed nodebb and I see much potential. But I am lost trying to do 2 things.

1. I want to change the signup message where people say they "confirm to data collection" -- In my culture NO ONE will click that. I just want it to say that you agree to the terms and conditions. ** Where do I find this message so I can re-write it? **

2. I need nodebb to be able to run ** ALL ** Iframes. It must be more than youtube, etc. Instructions are not clear for how I am to accomplish this. (Please remember english is not my language)
