/** | |
* This, as you have probably guessed, is the crux on which SMF functions. | |
* Everything should start here, so all the setup and security is done | |
* properly. The most interesting part of this file is the action array in | |
* the smf_main() function. It is formatted as so: | |
* 'action-in-url' => array('Source-File.php', 'FunctionToCall'), | |
* | |
* Then, you can access the FunctionToCall() function from Source-File.php | |
* with the URL index.php?action=action-in-url. Relatively simple, no? | |
