Dear Readers:

This issue of J.UCS is again a good example of the wide coverage of the journal: from quite theoretical to rather applied research, the four papers present a broad selection of interesting topics. I hope you will enjoy reading them.

As much as I wish you all a good summer (ahem, winter down under), I would like to urge you not to forget submitting high quality papers to J.UCS and to also encourage your colleagues to do so.

Yours cordially,
