New to WordPress

Hello to all

I just moved over from Rapidweaver and I really like the flexibility of WP.

Was hoping someone can take some time to help me set up my blog.

I would like to know how I can email everyone an update once i have posted a new entry.

I have downloaded the Newsletter Plugin, and i think i have it set up correctly. I can get new subscriptions and create a data base of emails. Just want to know how to connect it all together.

Thanks
