Online Course Feedback and Assessment?

My online course begins next week, and I am looking for ways to offer, promote, and access online course feedback. I want anonymous feedback from my students and the ability for my students to offer feedback to one another. The university will have some course evaluation at the end, but I like to regularly have opportunities to get more of an informal pulse on what is happening in the class more regularly.

How do others who teach online handle this?
