Hi, you can now attach .reason .rfl .cmb .repatch .rex and .rx2 files to your posts.
Remember that you need to close your Reason project for that save-file that you want to attach/upload. Otherwise it causes a http error. The maximum size for the uploading files is 10mb. You don't need to zip these files anymore. A quick way to share files on the forums.
I have attached a .reason file to this post to demostrate this.
