Showcase forum is good to have, at least it allow member to showcase their idea and content. Afterall, Scripting Forum is the most popular category in the forum. It enable more interaction between members.
On the other hand, advertising for product is fine, we have the forum to do it and the rules to follow. But the problem is that a lot member try to make use of showcase title to somehow advertise their product, bypass forum rules, and the forum mods have a hard time to tell whether they are actually just for showcase or advertising a product. At the same time, if a member planning to advertising a product, the forum would prefer them to use the IP Download System which enable forum to earn some commission to stay alive, however the payout is terrible, so most of the member just skip it and use other way (ex: showcase) to advertise their product.
Honestly, some time we just would like to hear some feedback about the showcase idea or content to improve it, not the annoying PM for Sales! How much? If you have "feedback", My Discord is xyz blablabla....
Members nowadays just love to create a showcase topic (or even attempts to join as staff team), just so that they could showcase their product and boost their sales.
Anyway, if really want to enable showcase forum, I really hope the forum consider to make a way to make it clear that the topic is either just showcase idea or showcase a product, remove they grey area. Members should be only can showcase their idea or content but shouldn't be allow to showcase a product there unless they followed the forum rules and earned the right to advertise it. Same should apply to graphic showcase forum.
Thx for reading, just my 2cents...
