Animeentries:Group Info

On each anime-page, right below the MyList status and above the episode listing, you'll notice the Group Info with compiled information on how many episodes that group has done, what their last episode was, whether it's complete or not and when the last episode got added to AniDB.
Furthermore if you have the anime in your MyList there will be a number in front of each group telling you how many files you have of that group in your MyList.
In addition to that info, when you want to vote or comment on a group for a specific anime, look at the last three columns: Rating, Comments and Action.

The average rating for a group is hidden until at least 10 votes are cast. Also, the list only shows 5 of the groups, so you may have to click "show all" to get the complete list.
