This is the first public (beta) release of the Memcache module. The admin stats still need a lot of work and patches are welcome. The basic machinery should be working well, however. Installation documentation needs some love.
This is a highly revisited version of the module that adds the ability to vote for nodes, and not just comments.
Both the javascript and the module are drastically different. Please give them a try and let me know!
You can pick which node types users can comment on, and disable the comment voting altogether.
