((Hello! hmm do I know of any place, um unfortunately I don’t and trust me I looked, but tumbr so far has been the best place I’ve ever found as no where else is quite as excepting or large^^, but if you have ideas feel free to share I know myself I Love love love to read little dabbles or dreams people have made or had and want to share, also if your shy about showing things on your personal try submitting the story’s though a g/t blog^^ if you follow them you can see it posted and well you will be credited though submissions no one who follows you will necessarily see it so in that way you could try it =D))
((If you want to try that way I have a side blog called gtventing you could go though^^))
There are a good number of VERY active forums if you don’t want to run a tumblog, too, depending on what kind of G/t you’re into.
