Need Permission to Create Tutorials?

[jrjones2009]

I'm in the process of creating video tutorials on the use of various wireless networking products to sell on Ebay and the Internet. Are there some simple guidelines I can follow to avoid being accused of copyright infringement by companies such as Linksys and DLink or should I contact each of them individually and get permission first?

You shouldn't have a problem with tutorials provided it's clear you aren't associated with the developer. Most usually fall within fair use or other exceptions.
