Stolen Blog Material

I have been spending countless hours working on my Real Estate Blog. I often stay up till 1am finishing posts. I have to admit that even after 3 months (and 50 posts), I am still learning all this world.

I have had a couple great posts that really took off. One in particular "Landlords: Read your leases" has been on a Blog Carnival, featured on Realtor.com, and a couple agents asked if they could link to it in their newsletters.

I was searching on Google Blogsearch to see how my post were hitting for key words. I typed in the above post title and found some realtor in Cleveland that cut and pasted my entire article word for word with NO reference to me. I would have been happy to give him permission to post it, but not as his own work.

What is my best course of action here?
