Dear Readers,
A happy and successful 2007 to all of you. I wish to draw your attention again to an enlargement of the Editorial Board of our journal. We are pleased to welcome three new members: Ramon Jansana (Barcelona), Klaus Meer (Odense), and Andrzej Roslanowski (Omaha). I would like to thank the outgoing member, Peter Koepke (Bonn), for the work he has done in supporting MLQ. Also, it is more than justified that the name of our Editorial Assistant, who always faithfully compiles the final layout, can now be seen at the cover. All readers are once more encouraged to contact the Editorial Office or a member of the Editorial Board with any suggestions concerning the contents or the editorial work of our journal. In particular, proposals for issues devoted to special subjects or conferences are highly welcome. In 2007 there will be two such issues: one will be dedicated to "Trends in Constructive Mathematics" and a further one will deal with "Computability and Complexity in Analysis". It should finally be mentioned that our publishing house is celebrating its 200th anniversary in 2007. During its whole history, Wiley has grown and evolved and has always been successful in serving the needs of its customers. So we can be sure to have a good background for the further development of our journal.
