As you may know, when people post URLs in comments, WordPress automatically appends anchor tags and makes them clickable. Unfortunately, for whatever reason, this is not an option for URLs posted in posts and on pages. I ran into this problem when working on another blog and posting several pages of URLs. I didn’t want to go through and link each one, so I found a plugin that will do it for me. It also gives you the option of making the links NoFollow.
The Automatic Links plugin will convert all URLs and email addresses into active links, so you don’t have to do this manually. This literally saved me hours of work and an enormous amount of frustration. Again, I don’t know why this isn’t even a standard option in WordPress, but I think it definitely should be.
