A fair few people like to put a link to an item/article into a post. The best way to do this is to cut and paste the URL into the post, using advanced editor rather than in the quick reply ,all you need to do then to open it is to just click on the link and it will come up straight away, whereas if it has been copied and pasted, in the quick reply mode the person reading it and wanting to go to the link, will have to highlight the link, copy it, open up a browser, paste the link into the address bar, then click on the arrow to take you to the link, making it a bit of a mission.
