My email info appearing in feeds and google search

Hi there,

I’ve set up a couple of WordPress blogs and when I write a post, my email is showing up in the RSS Feed, and under the title of the post in the Google blog search.

It is appearing like this:

Title of Post
by [email protected] (Irene Duma)

ACK!I just want my name to show up and I can’t find how to change this so doesn’t go out with each post. I set up my blogs with one-click hosting on Dreamhost. Any help appreciated.

Thanks,
Irene
