Forum:Read more?

I am an admin at the Alternative History wiki. Just today I have been noticing something called "Read more". It shows up in articles of sufficient length and has links, pics and text from similar articles. The problem is it appears in the middle of the page and IMO makes the article look terrible. I have been getting a lot of complaints from other editors and I want to know if there is a way to turn it off. Mitro 19:12, September 22, 2010 (UTC)
 * Can you give an example of an article with this? -- Random Time  22:42, September 22, 2010 (UTC)
 * I think this was a new extension that is still in development that was accidentally enabled for a couple of hours this morning. OwenDavis 23:35, September 22, 2010 (UTC)
