I still can't figure outhow to create a login for people to either add or edit t

I still can’t figure out How to create a login button or interface on the website for people to be able to either add their own or edit their own profiles
as well, as I still can’t figure out how to create a category hierarchy interface, where all of the different categories will show an alphabetical order.
And then people can click the category and see all of the list of people who are there and then they can click on the individual people the list and see their actual profile.

I have spent so many hours trying to read the documentation, and nothing is very clear, you really need to create videos as the documentation you created is very confusing.

So once again what I want to do, is create a login button, 4 people to create their own profiles and then be able to edit them, as well as on the directory page http://cibn.ca/directory/, be able to create a hierarchy list of all the different business types and then clicking on the individual business types drill down to the sub business types, and then from there be able to click on the individuals in the company who fall under that sub business type.

I sure hope this is very clear, because I am very confused. I once again have probably spent at least 10 hours trying to research this and nothing make sense at all., I have purchased C-map and list_type as per your email and still after 10 hours of researching this , Can’t Figure this thing out.
I do Internet marketing and WordPress sites and have been for 10 years now.

Once again, videos would be very helpful.
