lol is the first time that i hear something like that xDDD
I wouldn't like have a list with people that i don't like xD But with that it would be posible doing a counter about how popular is an user.
I think that a hate list is easy to make... it would be a list like buddy list, but i would have to list users from two list in the same page. isn't it? i will search information about $action foreach. I am newest coding in php.
sorry because my horrible english..
