hudge,
No problem. I would be happy to help. I already have a post that details what you are trying to do, it's called "My Login":

The mod works, but has generated a lot of requests for newbies with some of the code being proprietary (relating only to my custom buttons). I have though about revamping the post and may do so when I have a chance.
There are many ways to get a login page, but having an actual account paghe requires the integration and addition to the help duirectory and general.tpl in help. This is a great way to have an account center or area where a customer can access their details. PM me and I'll send you a link to some sites where have done this.
You can set if statements for membership or user type or even for specific users themselves. It is quite simple once the base template structure is setup. Unfortunately, at the moment can offer the full solution as it's a couple hours of work and $5 isn't motivating enough.
If I get a chance, I'll revist the "My Account Login" post and make it easier and cleaner for newer users. It's not too far off, but to get it right, you would stll need to have some experience or be able to recognize what the code is and says.
