Hey Sterling,
While a long intentional testimonial is best, of course, what I often do is wait until they send me an email telling me how great they think my software is. Then I'll ask if it's okay to use it on my Web site and/or marketing material.
I've even done some clipping and pasting to put the parts of their email into a better flow, and said, "Is it okay if I change your email to look like this, and use it in my marketing material".
Although some clients have said they didn't want me to use their name, I've never had anyone turn me down.
If you go to the testimonial page on my site -- (http://www.paulspafford.com/tests.html) -- you can see how I've treated this.
