The repository is a great idea. That stuff is teasing me like Christmas presents when I was a kid. Chinese tickle torture ain't got anything on GC3 waiting torture.
One quick suggestion though, content should be dated and/or sorted (or be able to be sorted) in order of posting. It took me a moment to spot the new picture that was added just recently of the small ship zoomed in. When the repository gets larger, it will be harder and harder to spot new content.
And apparently someone already asked in a different thread. Never mind the second half then.
