Hello there I'm new in vtiger. Now what i want to know is how to create costum module without using existing module designer or other same stuff. For example i want to create a custom module that will save the name and last name of a certain person. Actually I research in the internet, and I didn't find a clear tutorial on how to create a costum module specifically in vtiger 6. Do you have any good tutorial or link on how to create a costum module in vtiger 6 . Your help is greatly appreciated.
