Man, this is my 4th post and not a single response?

okay, another question!
So, i just copied the wp-o-matic plugin to the wp-content/plugins directory, and I can't see the "plugins" menupoint on my dashboard! So, how to build an RSS fed blog? And my second one, how to add a different template for every single blog? For example, if I make a new blog I'd like to change it's header image, and some colors. With preinstalled themes I can't do that, cuz if I change the desired theme's header image, it will change all on the blogs which uses this theme. Don't you wanna write a tut about this?

it would be a great!
