yes i did, couldn't remember where i found the info from as it was years ago and no i can't provide it but i must have done okay as I'm working in the industry.
I am curious, how did you learn then? Because I'm pretty sure you didn't wake up and know the answers?
I would argue going to the library and reading books, (which i spent a lot of time doing then and now) is exactly the same as asking a question to industry experts on the web. Am i not allowed to use books as a source of info as i didn't take the time or effort to produce and publish the book?
At the end of the day knowledge is NO good unless you can't pass it on. Your post was useless! please refrain for similar posts as it hasn't really helped anyone bar you and your ego.
cheers
