I love WebmasterWorld because I can ask just about anything legitimate and get a reasonable reply :)
I've a website for computer reviews. Many of the pages have old affiliate links that no longer work. I work alone and use freelancers to help me with many tasks.
Linkshare has the feature of adding a new user who can pull links. For the other networks, I could temp. change my password for the freelancer. What are the risks of allowing a freelancer to pull links and add them to my website? I don't see any, but I might be missing something.
