Default start Page

I’m running an adult website based around WP, and my host has requested that I put up an entrance page prior to accessing the website it self. I have got an entrance page setup, but whenever I hit the title to go to the home page, the entrance screen pops up rather then the blog itself.

I changed the blog address to include index.php in it, yet all the URLs then have index.php in it. One other alternative I can think of is to insert a cookie onto the users computer to have them bypass the entrance page, but that won’t work for people who don’t allow cookies.

One other solution I can think of is to include a ‘dummy’ folder in the blog address.

If you have any alternative solution they would be much appreciated.
