just my 2 cents worth as well...on top of the already ewwww, yikes, iframes.....it may not be very popular, as I found in my own experience that wordpress caused/allowed all kinds of security issues....i eventually just deleted the entire thing because I got fed up with trying to patch and fix it constantly....
