Deleting a multiple comment on a blog

I just wrote a comment on sngl's blog, and realize my grammar was retarted, so I posted again, and it still turned out wrong. I posted the 3rd time, and it finally sounded right.

Now, it looks like I was spamming his blogs, (which I wasn't). I'd like to delete them but there is no delete button, how do I delete the comments I have posted? Should I pm a mod?

 

thanks martin, you're so cute.
