I just wanted to say I have loved using HOD and using the message board. I have found it a good mix of hands on, good books, writing, narration, projects, etc.
I am not sure what # not to use reason this post is on but mine would be if you want to spent lots of additional money, time and energy after buying your curr then you won't like HOD!
and if you don't want a message board where you can get quick answers and ideas when you need them then you won't like HOD :)
