Alright, so I want my registered users to be able to do several things with the posts they see on my site where each post would have trigger buttons: Like and Don't Like
1) Mark posts they like
2) Mark posts they don't like
The site would then allow each user to Show/Hide all liked posts and Show/Hide all disliked posts.
This permits the user to see only what they choose to see: Stuff they like, stuff they don't like, stuff they haven't marked, or a mix.
To see an example of what I mean see: http://www.win-free-stuff.ca/new-contests
That site does run on wordprees. Looking at page source is a dead giveaway but the admin won't respond on how he did it.
Any ideas on how this can be implemented are welcomed. I assume it uses mootools or scriptaculous but I don't know how the buttons can be made to function.
