Site structure

Adds a "forward this page" link to each node. This module allows users to email a specific node or other entity on your site to a friend. You can customize the link text and icon and choose the view modes on which the link appears. You can also customize the email template to match the rest of your site. The module includes a report on which pages are forwarded the most and a log of all forwarding activity.

Similar Entries is looking for a co-maintainer.

Similar Entries provides lists of links to site content related to the current node being viewed. Links can be displayed in standard blocks or in custom views. Similar content is located and rated using MySQL's FULLTEXT indexing for MyISAM tables. FULLTEXT is a special query that helps find relevant content in other nodes using a natural language search that interprets the search string as a phrase in natural human language. Views module is only required for version 2.x.
