As I said, in that topic I did link back to an earlier post I’d made in the same topic. But that’s the exception.

I took no part in that discussion, and can’t imagine why I (or anybody else, frankly) would have linked to it.

I did take part in that discussion, and I did quote post #3, but the badge is awarded for post #2. As I said, I would have linked directly to the mentioned resource, had I wanted to, not to the post.

Again, I took no part in this discussion, and there is no indication I ever linked to it from within the forum. I have no recollection of so-doing - and in any case, I’d have been more likely to link to the original article.

Another topic I took no part in, and the only time I linked to that post, as far as I can see, was after I was awarded the “Nice Share” badge and got confused about it.

This is one of my own posts, for which I was awarded this badge. As far as I can see, the only reference to the post is where @Mittineague quoted it in the following post.

Another post of mine in the same topic; not linked from anywhere, as far as I can see.
Now, it is possible that I’ve quoted those last two posts in another topic (I get tired of constantly repeating myself), but I haven’t linked to them.
