Thank you, is there any way to edit the post to make them clickable?

I made a suggestion about this (clickable links in submissiosn), FWIW, http://news.ycombinator.com/item?id=1569226.

I think that's an interesting suggestion, and would be a useful feature. It does suffer from the problem that links would only become clickable after a time (having to wait for votes) whereas it's the first few views that really most benefit.

It's a great piece of thinking though - kudos. I've upvoted you both here and there.

Thanks ROG - I figure that at least the first few people view the link anyway before someone posts a "clickable" comment.

URLs in submissions don't get linked, URLs in comments do. If you want your URLs to be clickable, add a comment, just as I did.

This isn't a shot at you specifically because it happens again and again and again and again, but I'm constantly surprised, constantly surprised that people like yourself who have been here for months don't know the rules. It's something you simply need to know, something that you learn from spending time here, and wondering "I wonder why that happens."

This is off-topic for this thread I think, but the thing that constantly surprises me is that there is no mention of or direct link to the submission guidelines from the submission page.

And now I know!

I still can't figure out when the downvote arrow appears, though.

From the FAQ at the bottom of every page:

    Why don't I see down arrows?

    There are no down arrows on submissions. They only
    appear on comments after users reach a certain karma
    threshold.

That's the odd thing, I saw them one day and then they went away again. It's no big deal, I was just wondering, thank you.

No.
