Hi Kuribo, you can see how I rated the SotS scenarios over at sbginventory.com because I'm the only person that's rated them there so far.
I hadn't considered breaking down the ratings by user name. I'm always a bit wary about exposing personal information -- I don't want to have to deal with privacy issues -- but scenario ratings are presumably not particularly sensitive.
Collections might be a little more so; I guess I could add the option to make your collection public, in which case registered users could "impersonate" you to browse around (but not make changes, of course). That way you can opt in, but have to consciously make the choice to do so.
There are so many improvements and fixes that could be made to sbginventory.com. (Examples in addition to what you've mentioned: figure ratings; user comments for scenarios and figures; silhouettes for all the figures; figure URLs so you can link a photo of your painted figures; filter scenarios by keyword [#river, #fort, ...], etc etc etc. ) Time is the enemy for site improvements. Of course, if folks would prefer those improvements to battle reports, time could be found.
Including my ratings with the battle reports is a good idea. I'll try to remember to do that in the future.
