I'm going to be speaking at the Great Lakes Area .NET User Group in Southfield on September 17th. I will be giving a talk about Rhino Mocks, and the how, when and why to use it.
I am still putting the presentation together, so if you will be in the area and would like me to cover something specific, leave a comment. Even if you won't be attending, let me know if you think there are points which would be helpful for the people there.
