Thing 6 - Wikis

This was the best "thing" so far!! My husband needed an interactive communication tool for working with a fairly large group of people on many continents and a Wiki fits the bill perfectly. I introduced this 'thing' to him and we are now in the process of exploring which wiki site will provide the greatest security for sensitive material. I spent many hours on this thing because of exploring the different venues and especially appreciated the 'wiki matrix' tool. Thank you, thank you and thank you again for the opportunity to learn about this resource.
