The video explanation gives a very basic description of the wikis and shows just how useful they can be. After viewing several of the examples given to us, it is clear that very basic wikis can be developed without a huge amount of work and then the exact opposite - obviously some very talented people have spent a lot of time of their wikis.
I have found wikis to be an informal friendly professional way of sharing and may be very helpful when needing advice. As a member of a Queensland reference group we have found that the benefits of using wikis far outweigh the email system we used previously.
My little town of Tiaro has only a very small description in Wikipedia. I added a small comment about the new council region. My mission now is to update the description to give more information about our area.
