As the site administrator of Teaching Learning & Assessment, I was a complete novice in Wiki use when I set up this site. I did find that there was a certain learning curve to go through. I initially had trouble working out how to link pages and modify menu items. This did take a bit of sweating over, and I began to doubt the testimonials of other WikiDot users about how easy it all is. However, once I'd figured it out it was mostly plain sailing thereafter. A large amount of structure and content was developed within three or four days of the site's creation.
As with anything worth doing, you need a bit of patience and the willingness to learn from your mistakes. In fact, mistakes are reversible because all the edits you make are listed, so you can revert to earlier versions.
