I really don't remember, it's been a while since I did anything with vba. But I seem to remember that the installation instructions involved replacing or editing index.php, so maybe that had something to do with it. Come to think of it, I've only used vbadvanced with vb3 so it might be different with vb4.
I suppose you could edit the template to change the title to whatever you wanted. I believe it's adv_portal, under the vba CMPS group of templates.
Here is the adv_portal template. Can you point out what to edit here?
