From my view, I'm not certain it would be a great idea for gallery to be reputation enabled thus the 'unnecessary' word I mentioned in the previous post.
To be exact, so far I see gallery serve as either a collection of screenshots (for maps, skins, icons or models, which usually has a thread of the resources itself) or a personal collection of arts (and these ones usually go into the art forum).
I think this is more useful back in Hive 1 with the Social Group system (yes, that seemingly half-done SG system) where the Social Group posts can't be repped, but today I think the prev paragraph explains my view.
Of course, this is a personal preference and I don't mind with the final decision either way.
