Trying to set up seperate registrations

I am trying to setup separate registrations for models on my site and paying members. I copied join.php and renamed the copies memjoin.php and modjoin.php. How can I set these different registration files up so that the different registrations create the user as the specific membership levels I setup in the Dolphin ACP?

Also, how would I go about making the initial registration links given and used a one time trip so that noone abused the regi files without being led up to them?

Issue: 

1.  You want to create multiple types of profiles on yours site:

• Model Profile (Assuming Models are Free?)
• Paying Members

Here is your issue:

•   Dolphin comes with 1 Profile type and you may have multiple membership levels.
•   Dolphin utlizes $profileID to determine the membership.  By duplicating the join form, you would need to create an entirely new membership level and all new SQL Tables, along with if logged commands throughout the entire package to achieve your 2nd membership level.

Solution that is time & cost effective:

1.  Recode the entire site for this.  hope you have lots of time.

2.  Purchase the Profile Splitter over on Expertzzz.com from AntonLV and Dependent Fields from him. 

1. Obtains Multiple Profile Types
2. Fields that members complete are dependent upon the Profile Type and on other questions they answer.
3. Examples:  Male models answer one set of questions, female an obviously different set.
4. You can then set up different membership levels inside of the individual Profile types. 

This is the quick and easy way to what your trying to do.

Cost:  $190.00 US I believe

Time to put in:  1 night (it's done by Anton while you sleep)

Peace of mind knowing it works correctly:  Priceless

Can I not simply take the existing files and copy/rename/edit them to reflect the two different registrations? Whatever file adds the info to the db would just need to be doubled and edited so that depending on which regi you access you get a certain user membership/permission level. Then from there I see just editing the db tables and then editing the files that access the db info later. As in, when you view your profile information or passwords and such would need to be edited to reflect the earlier changes.

I wouldnt really need two profiles as far as I see it. The way I explained above seems reasonable to me and I have more time to throw away than money. Sorry but paying anyone else to do work I can easily do myself with some time is simply beyond foolish. :P


So that brings me to this; Where do I start? What files actually access the db? Obviously the config, registrations, profile editing, etc. Also, where would I start researching the part about making a user a certain level upon registering? I am fairly new to Dolphin, but have the newest paid version as of a few days ago. 6.1.6
