Voting Question: How do I find the strengths and weaknesses of Barnes and Noble?

I know all the risks, etc. But because of my age how would I go about investing in stocks? What's the best broker? And what type of account do you need (I assume my dad or mom needs to be on my account)? I live in Canada and a lot of the stuff online is American. I have been looking at a few sites and they don't seem to have a option to open a custodial account for a minor...any help there? I have invested in Microsoft in the past through their Direct Purchase Plan, it was a complicated process (I had to buy a single share from a gift site, get it shipped, then sign up with a custodian, etc.) But I want to invest in other companies aswell. >> full story
