Twitter & Facebook achievements intergration + LS

I searched, but didn't find a topic like this started, which was surprising...

Anyway, when the achievement system gets put into place, I would like to have the option to setup the game to 'auto tweet' or post on Facebook the update.

This, and/or have the ability to turn on/off the different types of achievements. Of course this would just be optional. :)

Another fun feature, would be to allow when a user unlocks an achievement to have it post into their current equipped Linkshell...

"X player has defeated 1000 enemies." or something of the sort.

Thanks for all that you do. :)
