Okay, I sent you a pm with details.  I didn't really want to use SSH, so I used FTP if it's all right with you.

Sorry I couldn't help much, unfortunately the doc seemed to lack any info on how to upload stuff where I checked.

Hmm strange. You may have to create a separate topic for that, though, so people can see it easier with the title and it might be helpful to others. I unfortunately have no experience on Apache myself, though.

If I run the apache server on my computer how do other people get to it?
Is it through my IP address? if so which one(LAN or WAN)

Oh dear me.  There's some things you don't want to mess with.  This might just be one of them.  Essentially, and depending on how your network is set up, you open a port in the router to access your website.  They can access via IP, If it has a static IP.  Your router will probably configure it with DHCP, and you'll probably have a local IP and your network will share the same global IP.  At least, that's how mine is set up. (I don't have the port on my firewall open, though)

Essentially, you can do something like dynDNS to get a domain name for free, and run a client that automatically updates it's IP.  If you open the port in your router, you're pretty much set to go.  Not that I would advise this, mind you, because of security and uptime issues, not to mention that the cost is probably more if people are accessing your network, and you're having to send a lot more data than you usually do.

What system are you using again? Not apache, but OS.  Look here.

Windows 7 32 bit Home Premuim

I set up an address now what do I do

What type of router/connection do you have?  Is it ethernet, wireless, linksys, etc.  Essentially, log into the router (like 192.168.1.1 on my network), and set up a port that way.  To make sure dynDNS is working first, go to another computer inside the network, and try to access your site via the dyndns name.  This should work inside your network.  If not, make sure that the computer is on the network, and that dyndns is updating.

Westell A90-9100EM15-10 is my router
My parents don't know the login for my router. How do I find it?

You reset it.  There is literally no other way.  Or at least, none that I know of.  I still suggest you have something else host it, but that's just because you might have trouble with security and such on your home network, and it can make your bill go up.
