With sticky motes you can embed your motes into any web page, so that you can provide a 'voice-over' to content that you share. Check it out here!
Step 1 - Enable the new UI mode (soon to be standard for all users)
Step 2 - The option to make your mote recordings 'sticky' is controlled by toggling the setting labeled ' Record on...'. Clicking that setting will enable sticky mote mode - by default this is now disabled.
