QUESTION Access/manipluate functions and classes to/from 3rd party plugins. Best practice?

ohh that form, yeah you can just use your own method or the default ones in the plugin, I think it has some custom registration capability i have used, but technically it is exactly the same if you just let the plugin handle the form processing so i do not see why you cannot just let it do it itself and use your own code to submit and show result. Unless it is using some nonce you need or something
