Very much FUN, I must say! Really enjoyed creating the Yahoo Avator.... this it is really neat stuff. (NO STRESS thats for sure). Tried the Meez also, it was okay. Don't think I will be revisiting that site much in the future.
The "Library Thing" was really cool.... and very user friendly. Now that I have created an account, I will be using that site quite frequently :-)
I registered and explored Rollyo today and created search sites for news and travel. Thought it was fine but don't think I'll be using it much at all..... I find that searching on Google is better for me.
