got an email from some guy regarding niftytutorials.com I replied with: he says: kinda random don't you guys think? what are your thoughts? his ideas are those that I was planning on doing anyway so i could certainly use his help. however i can't help but think he could be up to something (who knows what). thanks
Send him another rejection letter. In the future, he will probably bank off of your kindness and bond that was created through working together and ask for a small type of payment- and probably work his way up. The way I look at it, it is just another security threat, and possibly another division of your profits in the future. I say run the site yourself. You get more satisfaction that way.
zac makes a great reply here.. Definitely a security issue. You could document everything on paper, make him sign it as a volunteer and if something goes wrong you have papers. Or give him a small task to see what he does with it.
