I have created the basic functionality of a system - I can currently register, log on, etc. I'm currently trying to implement a settings page where users would be able to add a list of classes to their account. I've looked around on the documentation but it's a bit unclear as to what I need to use. I think Collections seem the most appropriate, but again the documentation is a bit unclear. Could anybody clarify on the usage of this (and whether I should be using Collections for this), as well as possibly a link to a more in-depth documentation/tutorial?
Hope this made sense.
