I would like to start to write some advanced plotscripts with complex commands in it. Where can I find help and support?
The Dictionary of Plotscripting Commands that comes with the OHRRPGCE has information about most plotscripting commands. This should be your first stop when looking for information about plotscripting commands.
After that, there is a section on the Castle Paradox forums concerning plotscripting - you should post there if you need more help. You can also ask for help in IRC Chat Questions like "How do I do advanced plotscripting" will not produce any useful answers. Instead, ask detailed specific questions about exactly what you are trying to do. Whenever possible, post the code that you are working on. You will get more help if other plotscripters can see what you are doing.
