Creating a blog is easy to me, as I have done them before. However, what was not easy was during the training over half of our computers wouldn't let us create blogs. My guess is because we were all using the same ip address at the same time?
I did not have a problem creating my Voki, but once again, had a problem posting it to my page, even following all of the steps accurately.
I did not face any challenges, besides the technology not cooperating with me. :-)
