We would like to take this opportunity to acknowledge the time and effort devoted by reviewers to improving the quality of published work in UMUAI. Authors often write to express their appreciation for the detailed and useful comments that we obtain for them. Only rarely do we receive complaints, even when the reviews are negative. This is a tribute to the spirit in which reviewing is undertaken for this journal.
