Dear all,
some updated information about this ever-growing newsletter, which has now 1184 subscribers. The statistics says that half of them regularly open the newsletter (and probably even read it !). Do not hesitate to tell interested ion trappers how to subscribe: there is an automated procedure on the website of the COST Action at www.iontraps.eu.
