Pro Site message

Hello,

I have setup 3 levels, Bronze, Silver, and Gold. I am looking at the Premium Plugins list that I setup and notice some say "Silver Only" and "Gold Only". I am trying to figure out how to change this text. "Silver Only" is inaccurate as it should say some like "Silver and Above" or in my case "Silver and Gold".

How would I change this text?

Thanks,
Rhek
