post links to remixing "chain" type projects and galleries (or forum topics even) if you want people to remix your remixing project Idea (especially if noone is remixing ever or have all stopped remixing it) you can post/link to the original, post the latest remix, or post a gallery of all the remixes, or post to a forum topic about your project even.

for example, I have a couple of remixing projects. one is called "3D sprite collage". you make a sprite with your picture on it and all of the scripts of one of the other rotating sprites, and maybe a few animation sprite things or something (don't make it draggable please) if you want to and then you can share it.
the most recent remix of this project (that wasn't deleted) was by lightamp1 http://scratch.mit.edu/projects/liphttam1/375900
