Well, you could always open up the header/footer user controls in the code and then modify them based on what you want. But you need to comment off the code that overwrites the default text by reading it from SiteTerms. That should do it.

Go to the folder BVModule\Themes\<your theme folder>\controls\. You will find Header and footer controls there. These are the ones you need to change. You can set some static text based on what you want in the ascx files. However, they will be overwritten in the code behind files. Open up the .vb files and you will see code as below :

lnkHome.Text = Content.SiteTerms.GetTerm("Home")

Essentially the text of your links is being set from the Site Terms. You will notice that both the Home links in the footer and the header are set form the same Site Term. So you can comment off one and hardcode is to what you want. Or, you could add a new site term and use that new site term for the text in the header and the footer. You decide whats easy and maintenable for you. Does that help?
