There are a few things on the secret project I'd like to comment on that may improve it in the future;
I feel like the main page can be easily spammed with resources from the same person all at once which kind of overwhelms and 1-2 resource users how many have some good stuff but it won't bee seen. maybe limit how many can be posted in a given time (like once every 15-30 mins) which can be done in xenforo permission (I know as I run a xenforo forum myself with this addon).
There is also a lack of categories
maybe spreading out the GFX to have logos, banner ,thumbnails, intro, outros along with one for renders(for people who make HD background images) as separate categories, this will make it easier for people to find what they are looking for.
