That's a great idea, i'll definitely be checking this list out in the future. And i'll probably join too if i ever make a showcase thread :)

Hello @DimitraG :) Thankyou very much for your kind words. Have fun simming! :)

@rosemow I was just thinking we needed this for some of the bigger threads! Great idea, rose.
