Limnu is a service that enables you to quickly create collaborative online whiteboards. On your Limnu boards you can draw, type, insert images, and chat with collaborators. Every whiteboard that you create on Limnu can be saved as an image to review later.
Limnu's free service allows you to edit your whiteboards for up to seven days. In the free version of Limnu you can have three active boards at one time. The free version doesn't limit the number of collaborators that you can invite to work with you. Inviting other users can be done in two ways. You can invite other users by email or you can invite other users by sharing a link to your Limnu board. You can disable sharing at any time.
Applications for Education
Limnu lets you create sticky notes on your whiteboards. Students who are brainstorming together could apply sticky notes to their Limnu board then sort the notes as a group. The drawing tool in Limnu could be used by students to show connections between ideas in their sticky notes.
