if you buy a template from mccodes its everything you need to get started on scripting:
-Internet Info Table
-Multiple Polls
-Hidden Polls
-CAPTCHA Test on Registration
-User can be rewarded an item and/or crystals for succeeding a crime (as well as just money)
-User can goto jail for failing a crime
-Jail added
-Crime XP system added
-Improved User info on login
-Attacking, mugging, leaving, hosping etc.
-Major Item Overhaul
-Database drivers
-Improved cronjobs
-Contacts list
-New fresh Skin
-Settings table which means you don't have to edit files such as donator.php to fill in your PP address or header.php to change your game name, you just set a setting =)
-General Optimization (reduced Queries in a lot of files)
-Player Notes
-Lucky Boxes
-Send Crystals (can be turned off/on in settings)
-Bank Xfers (can be turned off/on in settings)
-HallofFame Filters (non-donators, donators, or all users)
-Delete All Events
-Fully Featured Staff Panel
but it costs $300

thats the way i picked up , editing scripts , messing around
you soon be able to script even more
