We make an educational content sharing site called Wordwall that allows educators to author interactive activities and embed them into third party sites (e.g. Moodle)
We're offering free licences to Moodle developers with a view to getting some feedback on integrating Wordwall activities into their Moodle pages. We'd like to make this a more seemless and useful experience for our Moodle users.
You can sign up here if you want to get a free account (normally it's £72 a year).
Please drop me a line if you have any good ideas and whether you think it would be of use to your Moodle communities.
