From your Blogger Dashboard, go to Settings > Search Preferences and look forCustom Redirects option, then in the From: box enter a forward slash - "/" and in the To:box enter the page name which is after the blogspot.com - for example yours would looks something like "/p/Forum.html" (you should add the slash before of it here too). Now thick the "Permanent" checkbox and click on the 'Save' link, then press the 'Save changes' button. Hope it works!
