The limits of this extension is just your imagination...
I cannot wait if this extension is updated.
I don't know why this extension hasn't been rate yet. I was looking for something simple fot my facebook fanpage, and I tried others modules, until I found this one. This module works right out of the box, and has 2 display positions, sidebar and standar... very highly recommended =)
