Interview People via the Web

I have been looking for a free service for a while to interview people via the computer.  The most I have found is ones that allow a free month.  But thanks to "ShellTerrell" whom I follow on Twitter (from Germany), I found Wetoku.  All you do is give a link to the person you want to interview and get online at the same time and push "start."  Immediately you have a link and embedded code to put on a website.  The only disadvantage is that it is not as good quality as some of the other paid ones, but for the price it is excellent.
