I have a site where the possibility I have users to register to access a portions of the site.

This area, I will have to create a custom registration for it.
i.e. Company Information and Agent Information

But lets say in the future, I create another section in my site where all I need from the user is just Company Information, no Agent Information  but the details of company Information is totally different from the other site.

Is it possible to create 2 type of registration processes?  I have DNN 5.2.2 Pro.

Thanks.

Let me try this scenario if this is possible.

I saw that its possiblee to setup a custom registration at initial setup by changing the profile properties.

But after they register, I can get an e-mail notification that a new user has signed up. I can assign them a role. Then as Admin send them an e-mail notification that their registration is confirmed.

In my scenario lets say we have two types of roles besides (host and admin): a Company Role and Agent Role.

Now based on a specific role like Agent Role, when they log back in initially the first time, I can prompt them to fill out Agent Information Data that are REQUIRED before progressing to the next page which is designed for Agent Role viewing only.

But if a user is assigned a Company role, no additional information is required upon initial logging in and can proceed throughout the site, but they cant view any pages deemed for Agent Role Users.

Is this possible? Is their a tutorial for this?

I would look at Dynamic Login and Dynamic Registration. 

Thanks to your reply and viewing the Tutorial by Lee S. for Dynamic Registration, it seems that is the way to go.  I purchased the module and looking forward to piecing the parts together.

Thanks.
