Wiki's

I have spent the last few days exploring the various common wiki's. I've come to the conclusion that each one has it's place. Before you decide on the one to use...know what you want to do....do you mainly want writing, photos, or just collaborate with others. ...how do you want to organize and how flexible are your users....right now I'm using several different wiki's for different things....organization is important for school, downloading photos for family and ease of use for users for my church group. I'm glad there are different wiki's out there to look at....and I'm glad they are similar enough for me to go back and forth between.
Take a look at some of my wikis at http://www.tallowoodacteens.wetpaint.com, http://pgpsbisd.pbwiki.com , http://rummelcreek.wikispaces.com and http://www.covenantcares.wetpaint.com. Lots of choices.....
