OK, I think I know what you mean now. You want to change the title for the html page and not the title of a site. I did a little digging and here's what I found.
The text "Home" comes from this xml file (on my rig):
C:\Inetpub\wwwroot\wss\VirtualDirectories\80\App_GlobalResources\wss.en-US.resx
<data name="multipages_homelink_text">
<value>Home</value>
</data>
By default, Sharepoint creates the title text by concatenating "Home - " + site's title. So if you want to have totally custom text, do the following:
Open this file for edit:
C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\TEMPLATE\SiteTemplates\sts\default.aspx
Next, replace the sharepoint title with your custom text:
Before:
<asp:Content ContentPlaceHolderId="PlaceHolderPageTitle" runat="server">
<SharePoint:EncodedLiteral runat="server" text="<%$Resources:wss,multipages_homelink_text%>" EncodeMethod="HtmlEncode"/> - <SharePoint:ProjectProperty Property="Title" runat="server"/>
</asp:Content>
After:
<asp:Content ContentPlaceHolderId="PlaceHolderPageTitle" runat="server">
Your custom text goes here...
</asp:Content>
Hope this is what you're looking for!!!
