I get a feeling that sometimes people don't necessarily look at the comments on the side that people put on their projects, so why not put it right in the project itself? I said only scratch links because otherwise, people may put inappropriate links in their project. So there could be a block that would be like "when clicked, go to link" but you could ONLY click it so that people wouldn't forced to do something they don't want. So, who's on board?

From what I hear, they might do something like this in the next version of Scratch!
The only thing I can think of is you can trick someone into downloading a project by adding /download to the end of a project's URL.
