Gary and Sai, I’m responding more with a question than a response as I do NOT now conclusively or tested this. My question is whether this would work with external links, given that those projects are opened in the background. The question is whether Project is smart enough to open the successor project/task even though the user does not have permission? If it can, does the PM know of the project (one of the original questions). At a minimum it might be something to test.
