Jive's main purpose is to enable managers to form and dissolve groups as needed for specific tasks and projects. It collects the working profile of all the employees in a company to make it easier to find the right people to assemble for a project. It also provides a way for employees to submit ideas and vote for the best ones. Jive's Mobile Module (free for the iPhone) lets you browse recent activity, post a response, update your status, and even upload a photo to a new blog post. You can participate in discussion threads and communicate with coworkers through their profiles. You can also download contact info from Jive into your phone's Address Book or transfer contacts to another phone.
