welcome. yes it is possible. when I find a link that pertains to the mental problems I am posting or replying about I go to that websites page then at the top of the page where it says the website and page address I highlight it with my curser then right click on it, copy. then come back to psych central where i am writing my post and right click, paste the link in my post.

that said some forums require we post links to articles or videos in those designated forums. to do this is the same process but the post has to include your opinion of the information in the link. the specialized forum for music videos is here....

and the link for posting current events article links\posts are here.....

you can also go to your profile and place a link in your "signature" for example I placed three links in my profile signature for easy access. my posts frequently contains some part of all of whats in those links so I found its easier for me to locate them in my signature line rather than having to scroll through pages and pages of forum pages to find out where they are.
