I've been working with this mare for my mom. She's been going very well, except for a single problem: not responding to my "forward" cues. So, after verbal cues, sqeezing, tapping and kicking, I gave her some... encouragement, and let her go with it. I didn't stop her as soon as she took off, and I slowed her back down into a nice lope.
I just had to share. Sometimes, things like this are necassary, even though you might not like doing it (I don't) and other people might not like it, but when it comes down to it, you gotta do what you gotta do!
