Lets students create and select groups. Features:

• Students can create groups, give them a description and set them password protected, if wanted
• Students can select and join groups
• Non-editing teachers may be assigned to groups
• Teacher can export course group list as a csv-file
• Full compatibility with basic Moodle groups: groups may be created by other means if needed, supports group assignment submissions etc.

Thanks to Pirkka Pyykkönen, Petr Skoda, Helen Foster, Daniel Neis Araujo and other contributors, on whose earlier work this plugin is based on.
