I need instructions on making a website similar to Myspace.com  The
website needs to work like this: 1. A user creats an account, posts a
picture and creates a short profile. 2. The user selects which area
they live in, and in that area, which local bands are their favorite.
3. The user needs to be able to see the profiles of OTHER users who
also like the same local bands in the same area. 4. Users need to be
able to send a "message" (not an instant message) to any other user on
the site who has the same taste in local bands.

I am not a web designing EXPERT, however I do know a lot about
computers and basic web design. If someone could please explain the
best way to make a website like this (I want to make it myself without
hiring a freelancer to make the entire page) that would be great. I
currently own the Macromedia MX package. (includes dreamweaver) Thank
you all.

You're talking about web programming, not web design.  There is
programming involved in creating an interactive networking site like
the one you suggested.  There is some stuff built into Dreamweaver
that will let you store and retrieve information from a database
without programming it yourself, but I've found that it isn't
sufficient to do what you want.

As for providing instructions on how to make a website similar to
myspace, I don't think anyone would ever be able to provide them to
you.

So I would suggest learning more about web design, but more
importantly learning about web programming.  You can learn some of
this stuff for free from places like W3Schools
(http://www.w3schools.com/).  Popular web programming languages for
something like this are ASP and PHP.  You'd need a database to store
all the information too (MySQL is free and is commonly available from
webhosts).

bwgraham-ga is correct. Your best bet is to learn ASP.NET and SQL...
You'll need Microsoft's Visual Studio software to create ASP.NET pages
and I'd recommend Visual Basic (VB) as the more intuitive language to
learn (as opposed to C#).  Keep in mind there is a LOT to learn
here... this is no 3 week project. I'd say more like 3 months to get
your feet just off the ground if you're not a programmer and you spend
a ton of time learning the ropes.  In the ASP.NET pages you'll use SQL
Statements in order to grab and write to the database.

The best way to learn SQL is with this tutorial:

A great way to learn ASP.NET is with the ASP.NET resource kit.

You'll also need to get a web host with Windows and a SQL database.

I suggest to use php with mysql, both are gratuitous.  php is more
easy than asp. if to want aid (it will be to make in php) mine msn is
reberttomaz@hotmail.com I has a system of messages similar to this
that you want to make being thus I you arrange you the code source of
it.
