I don't post in the forum often but I've been interested in the rating section of the site for a while now. I like to contribute to the site but sometimes scanning and adding checklists can be time consuming and onerous. When I have a bit of spare time I 'roam' around the site; looking at the set from the Card of the Day, looking at the sets from the 'New Galleries' and going through newly added checklists from cricket, Aussie Rules Footy and sets that are themed to my interests and rating them.
As my collections is quite ecclectic the Rating component has the potential to guide collectors into sets that could be of interest. Obviously everyone has different tastes but it might help some in picking which sets to chase.
