I want to write my own package. Where can I get help becoming an author?
To start with you'll need to know at least a bit of php (https://php.net). Then check out the stickies in SMF Coding Discussion (https://www.simplemachines.org/community/index.php?board=60.0) and the Function DB (https://support.simplemachines.org/function_db)
