I was looking at gallery forum and i thought it would be nice if we had more thumbnails displaying instead of 5.I find those thumbnails already abit too big so I think one could put 5 more without occupying more space.
I also was wondering whether it would be easy that the second row of thumbnails is not handpicked from gallery forum but rather best rated finished section. So the second row is calculated by user ratings.
The above is just a suggestion in the case that easy to implement and you wont lose sleep over it. I think already the forum looks great , but throwing another suggestion certainly wont hurt.
