I like the idea of Wikis as I have just been through the “email jungle” with organising the school fair. This would have been a very handy tool. If I used it I would have to keep in mind that the general public can access it. Google Docs would be the solution to this problem.
Nings can be another way to find resources that have been tried and tested instead of muddling through lists. Being part of a community with similar interests can be extremely beneficial and I can see that it could work very well in the classroom but probably for older students.
The tutorials to create a Google Site seem very straight forward and I will perhaps attempt this when I have a reason to. Google sites and blogging seem to be quite similar.
