CLiE, LASER and the LAGB are looking for existing resources to add to their websites. Specifically, we're looking for online or downloadable games or activities that promote understanding how language(s) work, and linguistic analysis and pattern finding exercises like the Linguistics Olympiad puzzles.
If you know of of such resources please e-mail Graeme.Trousdale@ed.ac.uk and/or chair@clie.org.uk (specifying whether the resources are suitable for school children of primary or secondary age).
