I missed that… what you also could do is create an account on Codepen or jsfiddle and post an example with only the link. Then later remove the example.
The forum’ll end up with a dead link but I guess that wouldn’t be the first time.
Edit – assuming one can also delete fiddles, I really wouldn’t know.
And I can’t even check on a Mac myself by the way but just have a general look at the code.
