DizExplorer03's "Magic Mayhem" remains one of the most memorable toyboxes in my mind because it utilized so many of the logic toys well. It was such a well-told story and it flowed really well.
I think the ability to create original, high quality content is what makes the community better as a whole.
I think "Summit Fever" can be a good and bad thing. It is driving competition so people are making better boxes, but it's also causing others to focus more on the quantity of boxes than the quality.
I don't mean this in a demeaning way. Since the point of this thread was to offer feedback, it just seems like a good place to mention it.
