Here’s a little plugin to fix an annoying problem. Do you ever have commenters paste an entire URL into their comment as plain text, rather than putting it in <a href="..."> tags? Or if they do use the a tags, do they still use the URL as the link text?
Sure looks ugly when people do that. Here’s a little plugin to replace URLs that occur in comments with [link]. We don’t strip the URL–the word [link] will be clickable–we just make the comment prettier. Enjoy:
