Providing member's area access to web masters has been benificial, for us: they get to see what they are promoting, it saves me time from gathering semi-unique content (different packages for each web master) and they tend to work harder for us.

Once the web masters uses up all our free content, I'll provide them with access for one-day (more than that is not really needed, as far as I am concerned) to all sites . Not many abuse the generous offer, but when they do (such as streaming entire videos, multiple times), I'll either send them a reminder of what they are suppose to be doing, or I'll simply terminate the access.
