Editing username field

Hi there,

I’m trying to figure out how to edit the registration form so that the username field has some text just after it reminding new users about important information - is this possible to do through the s2members plugin, or would I need to edit a PHP file in WordPress?

Never edit a core WordPress file. It will get overwritten on every update.

I assume you are talking about placeholders. If so, see this thread: Add placeholder text to registration inputs

If not, please explain in more detail what you are trying to do.
