Hi, the reply fuction for notes is working fine for me, what is it doing or not doing that causes you to say that it's not working?
As for the differences between notes and messages, the biggest is that notes are public, so you should be mindful of what you put in them, because everyone can see them. They are intended for just quick greetings or questions, much like comments on one's Myspace profile or Facebook wall. They really arent up to speed for indepth questions or communications.
I'm a bit uncertain about how the Notes feature is supposed to work. At present, I have a couple of Notes from erik, but the Reply features doesn't seem to work. And if Notes are supposed to function like Messages, then what is the difference between the two?
