Gonzo, if you saw how mass produced front ends were developed you'd see why the connection between tours and members areas has never quite *clicked* LOL
the tour is built based on highest possible conversion and the members area is built on 'how much can we cram in here' ...
its a business plan that only works as long as surfers are stupid
here's my retention tip ....
i think affiliate programs should start skipping building tours, give an affiliate access to the members area and say 'build your own tour' based on our content ... every affiliate we've let do that has excellent traffic/stats/conversions ...
