There have been a lot of scripts regarding anagrams and word lists released recently, so I thought it would be a good time to collect some handy word lists. Please post if you have any good links. Also any lists relating to *phrases* i.e. common multiple-word constructions, in different languages (translation into English not required), would be useful. Thanks.
