I recently got a tumblr at
http://the-excel.tumblr.com with the intent of replacing my front page at
http://whatistheexcel.com with it. I want to replace only my WordPress blog on the root of my domain without having the user seeing the tumblr URL but not lose my hosting. Pointing my domain's nameservers to tumblr is out of the question. The best solution I can find is to make a page with nothing but a full-size iframe, which I did at
http://whatistheexcel.com/test but I want all external links on tumblr to open in the parent window, which I can't figure out. So every link opens in this iframe and the URL is fixed at
http://whatistheexcel.com/test/index.htm. Is there a way to fully replace a page with another without having to resort to a simple URL redirect or do security practices forbid that sort of thing?
