FitVids

This module uses the FitVids.js library for fluid width video embeds (e.g. flash video in <iframe>s). You don't need it for pure HTML5 videos.
It supports YouTube, Vimeo, Blip.tv and Kickstarter by default, and can use it with other video providers like Dailymotion or Viddler.

Smart Trim

Smart Trim implements a new field formatter for textfields (text, text_long, and text_with_summary, if you want to get technical) that improves upon the "Summary or Trimmed" formatter built into Drupal 7

Real Name

"The RealName module allows the administrator to choose fields from the user profile that will be used to add a "real name" element (method) to a user object. Hook_user is used to automatically add this to any user object that is loaded. It will also optionally set all nodes and comments to show this name."
