Hello, Let me explain my situation... I am trying to design a custom field for a Steam Id for Steam Dedicated Server registration. TCAdmin and TCAdmin Advanced already use a lot of these features, but I would like to have more functionality by having the WHCMS installation query a separate database with the information and make a few changes to it. I am not sure how to do this. I am aware of the action hooks and the different kind of modules, but I am not sure where to start. I do know PHP, java, ajax, and MySQL, so I don't need anyone to code for me. I really would just like information on where to start coding and where to put the files. I am not sure how to create a module and even if I do, what kind of module to use. Any help would be appreciated. Thank you.
