Parallel universe website that has the plot to BTVS and spike fixes his mistakes

Somehow Buffy and Spike stumble on a Buffy fan site where people talk about the different episodes of Buffy. They spend the day going through the website to figure out how much they know about their lives. Spike joins and uses the people to fix everything that he will do wrong and him and Buffy end up together. The site disappears after a while.

Lost in Cyberspace - you can find it at sinister attraction archive. I forget the name of the author.

Thank you
