Convos

Convos is a web-based service designed to simplify the process of creating, managing, and interacting with private, online groups.
 

Convos Groups are a simple, universal way to organize a group of people online. Groups can be large or small, ongoing or temporary. Starting a group takes 10 seconds and every group comes with tools such as Messaging, Schedule, Tasks, Files, Pages, and Directory.
 

With the full-screen, Flex based interface, Convos users can quickly manage their interactions across all of their Convos Groups. There's no advertising to get in the way and no pages to load. Everything takes place in a modern, 3-panel interface.

Convos is free to use with upgrades available to allow users to manage more groups and increase the capacity of any single group. Plans start at $4 / month.
