Perfect!Oh yeah, of course. I've spent a lot of time thinking about copyright, and I've managed to stay legal with this pack.
More or less what I said was "Here is a guide to steel: <link>"
Is that good enough?
I've just had to have a 'discussion' with a couple of people about attribution recently. You're perfectly okay. Linking is always good. There was just this individual who did a copy-paste and tried to claim it as being made by that individual because 'it isn't the original anymore because I changed it', when the only change was the attribution. This is not what you are doing, so you are A-O-GUD!
