From Bulbapedia, the community-driven Pokémon encyclopedia.
However, this soon changed. With a good heart that is always willing to help, Meowth346 suggested that the Pokédex be written in PHP. Shining Arcanine tried to write a PHP Pokédex, but initially didn't grasp the main concepts of the language. So he continued writing his Pokédex by hand in html. Then after a few more conversations with Meowth346, he asked for help. That was the major turning point in Pokémon Fan Universe's history. Through AIM, Meowth346 helped him write his first script, a Pokédex. At first it was also rather unimpressive but lacking as it was, it did have an entry for all 251 Pokémon (as was then the number of known Pokémon in the world). And over time, Meowth346 helped him with content (moves and a few minor lists, which were greatly appreciated) and in doing so taught him the concept of his Pokédex's then current storage system (which was rather inefficent). After a few months of help a Pokédex started to take shape and Shining Arcanine could write content for it on his own. Then on March 16, 2003, the Pokédex went live and for the first first time in its history, Pokémon Fan Universe had unique visitors by the hundred.
Then about 8-11 months after arriving at Always Web Hosting rising with rising bandwidth costs, Shining Arcanine decided it was time for Pokémon Fan Universe to leave AlwaysWebHosting and go elsewhere. Pokémon Fan Universe's next host was The Forum Host, which sponsored Pokémon Fan Universe giving by it free webhosting in exchange for a text advertisement at the top of every page on Pokémon Fan Universe. Unfortunately months later, it went under and was taken over by another webhost, whose
number is currently unknown but is believed to have also went under. Pokémon Fan Universe didn't stay until that happened through. After learning about 1&1 Webhosting, a webhost that was giving away free 3 year professional packages, Shining switched so that Pokémon Fan Universe could once again be ad-free in December 2003. Unfortunately 1&1's servers were insufficient to serve Pokémon Fan Universe's visitors so in January 2004 Pokémon fan Universe switched to a webhost that was created for the sole purpose of giving away cheap webhosting. It later evolved into A Small Orange Software, a commercial business but fortunately this provided Pokémon fan Universe with a reliable and inexpensive webhosting and fortunately was its last host move.
In the time that followed, Pokémon Fan Universe was under constant development and recorded days of 2000+ unique visitors. The rest is history.
