Yes, Allfreechips is well a frankenstein of web site coding. I created it over the years and learned the right way of doing things after making most of it. It was first coded as a stand alone site. Then Coded to work with phpBB2. Then now coded to integrate with vBulletin. There is a long list of updates I need to do to make things better on it but its 100% custom.
The data for the site is also in a way I can export the database to all my other sites as well making updates simple.
