Link Overlay vs Attachment in C4R

[steve]

I would like to find a discussion of whether to use collaborate/manage links/Overlay vs Attachment in C4R.   Can you tell me (or point to an arrticle) that discusses how these 2 behave?

Hi,

The difference between Overlay and Attached is described in this article:
