Sorry for the delay, but I was on vacation and we don't actually monitor/respond to Discussions filed in most Groups. If you want help, you should be filing a a Discussion/Question in the Jive Support Space or a Support Case within your Infusionsoft Group. That said, all of the text on the page can be customized via Admin Console: People > Settings > Single Sign-On > Login Entry Page. However this page is not exposed so Community Administrators within Cloud. So you will have to file a Support Case in your Customer Group and let us know exactly what you want your login page to say.
Page Title: Welcome to Jive

SSO Login Title: Employee Login
SSO Login Text: Jive employees, click here to log in.
Non-SSO Login Title: Non-Employee Login
Non-SSO Login Text: Not an employee? Click here to log in.
Though it looks like you've already done just that: Edit login page.
Thanks for your help Nathan!
