How do I change/add the following text?

[boozecrooze]

Hi,

I'm having a great time in learning how to use vbulletin. I'm getting stuck every once in a while, but this site has helped a great deal.

1. is there a way to change the word "Forum" (as in the bar above the list of forums that also shows "Last Post", "Threads", "Posts") to something else?

2. How do I add "Sub-Forums" in my forums descriptions?
Example:
vBulletin 3.6 'How Do I' Questions (54 Viewing)
Use this forum to ask questions about how to do things in vBulletin 3.6.
Sub-Forums: vBulletin 3.6 Quick Tips and Customizations

Thanks so much for your help!
