I have a question that I need an answer to before I unintentionally get into trouble.

If I ever write a tutorial for this site or for another site (the matter as to whether I'll actually ever write a tut is another topic) I have to overcome the problem that several of the techniques I use aren't actually mine and have been adapted from other people's tuts. Would it be alright to include these techniques if i reference the tut of origin and/or have the permission of the original tut creator?

P.S: I'm sorry if i've posted this in the wrong place but since it isn't actually a tut i didn't think it belonged in the tut section.
