I have also found those annoying forms all over the place like when trying to view a webinar etc.... It drives me nuts & most the time I dont even bother.
What I don't get is that I am already logged in so DNN Corp knows who I am so why do I have to tell them everytime I want to download or view something.
I hope they rethink this soon as it is very bad marketing that will turn people away very quickly.
DNN Marketing please read the follow before creating long annoying registration forms when you already know who we are:
