Changing root element on navbar breadcrumb

[challii]

Dont know if this is possible, but im sure other people must of tried in the past.

I'd like to make the root element of the navbar thing to be site.com, rather than site.com forums.

So if you were browsing this thread it would be showing up something like:

vBulletin.org > Forum > vB3.5 Modifications > vB3.5 Modification Questions

Now I can manage to get it to show the vBulletin.org bit with an easy bit of template modification. The downfall of this is in two specific areas:

1) The forum home, it doesn't take the added in code
2) The site homepage. That doesnt think its the homepage.

Does anyone know how to fix this?
