Hoi, People who edit on WiktionaryZ now have the possibility to add new Expressions and new DefinedMeanings. This is one piece of functionality that has been most eagerly awaited. What amazes me most, is that there is already so much content, check for instance this list: http://www.wiktionaryz.org/Portal:eng/List_of_1000_basic_English_words
To remind you, WiktionaryZ is still very much in a pre-alpha stage, this means that editing is not there for anonymous users, users that want to edit, have to add their Babel template information and have read the [[DefinedMeaning]] article.
Thanks, GerardM
