I spent some time to day with Jim Stout, the CEO of Invoke Systems. He asked a question, and typical of the way I do things, I told him the answer was on the blog... And that it was easier to get pushed information that pull it down... :-) Well Community Server has a great feature...
1. Make sure you are signed into blogs.msdn.com In the case of my blog, look in the top right hand corner. If you are not signed in, go ahead and create a user account.
2. Once signed in, in the top left hand corner, look for the Email Alerts link.
3. Select the option that makes the most sense to you. I want every comment, etc... but most folks will probably only want the second option.
Now, every time a blog post is made, you will get an email from email@example.com with the post's contents.
