Disclaimer: I know that this would be a pretty major change, but it seems useful to me.
Lately, a massive amount of people have been posting builds, art, and scripts in the #help-and-feedback:cool-creations category asking for feedback. The purpose of this category (per the About Cool Creations topic), is as follows:
According to that, what these users are doing is perfectly fine - and it is. However, in this overflow of cool creations topics, the other development support categories (#help-and-feedback:art-design-support and #help-and-feedback:building-support) are being used significantly less - in fact, looking through the new posts, there is a 6:1 ratio of cool creations posts to building support posts.
The reason that we have support categories for different forms of development is in part to avoid a massive amount of new posts in one category (I understand that that may not be the main reason).
I suggest that the Cool Creations category be reserved specifically for showcases and complete works. This will help organize development support posts (building/modelling and art go to their respective categories) and reduce the massive amount of new posts in this category.
Furthermore, I suggest that the About the Cool Creations topic be revised to read:
The forum has sufficient categories for development support posts, thus #help-and-feedback:cool-creations should only be for displaying and discussing showcases to improve organization and reduce excessive posts in said category.
