Robot Co-op create  these thress websites:43places,43things $ 43people.You just have to register in one of three sites,then you can login in the other sites,which is very convenient to us.I get an ID:andychen.

43places introduce some places you wanna travel to but never do it yet,and you can give an introduction about places you are familliar with to others who are interested.

43people just like a place you can make friends as you like.43things let you know who have the same wish with you to do something.

43 serial sites are very funny and interesting in a word.
