Ever wanted to put nodes or other content into popups or tooltips?
The popup filter allows the insertion of tooltip-like popups of:

• text, nodes, blocks, menus, forms, views and php-generated content wherever input formats are applicable
• node reference fields in node displays and views.

Instructions

• Install the popup_filter module
• Insert [popup] tags in content, and set the input format to "Popup filter"
• Install the popup_filter_ui module
• Go to admin/settings/popup-filter and setup formatters for node reference fields (if you don't like the defaults)
• Select the formatter at the node field or view field display configuration

Popup goes the content.

What is a "permalink"?

Wikipedia defines permalink as:

A permalink, or permanent link, is a URL that points to a specific blog or forum entry after it has passed from the front page to the archives. Because a permalink remains unchanged indefinitely, it is less susceptible to link rot. Most modern weblogging and content-syndication software systems support such links. Other types of websites use permanent links, but the term permalink is most common within the blogosphere. Permalink is a portmanteau word made from permanent link.

This module allows you to add a permalink to any node type. The link will be displayed as text that is easily copied from your site so that someone can link to the node. The link text is to /node/NID or ?q=node/NID instead of an alias.

Best reply module allows node authors to mark a particular comment as the best reply. It aims to encourage quality comments and to give some recognition to people posting quality responses.
