Setting the title of a blog post

Hi everybody,

I want to set the title for a blog post to my site name, so users don't have to type their own title. They only have to fill out the text part of a blog post. Is this possible? and if it is, how? 

Thanks.

Just a few thoughts - keep in mind that the blog module is setup for users to create their own blogs, and as such, they may have a specific title for that blog. I will just use me as an example. I am working on a site called cvp71.com - specifically for Crown Victoria Police Interceptor owners. Now a user may want to blog about how they changed the engine in their vehicle and mya want to call it Engine Overhaul (or something). To have it hard-coded to the site name may not work out all that well. Also, the title is used to create the links to get to the blog.
