Usually when you click a permalink (“read more”-link) to a post, the link contains a “#more-” at the end, making the browser jump down to the “readmore” mark. You might not want this behaviour, so this plugin removes the anchor from the link.

Remove More Jump

Removes the anchor from the permalinks ("read more"-links), so you don't jump halfway down the page.

If you are using a second WordPress-installation in a subdirectory and want it to be fully integrated it into your main site to prevend struggeling with two or more Sitemaps in your Webmastertools,
