This should be put back in the sandbox Sin puntuar aún
According to the policy, add-ons must be accurately described. The description is useless. I installed the software and it doesn't have a place to enter any blog urls or anything similar. It has no preferences via the Add-ons menu. It seems to have something to do with some website, but the website has no documentation on it. When you click on the help, it takes you to a page that says it's not ready yet.
How this got public, I don't know.
