We are very happy to see that so many worldwide (52 different countries!) show interest in Dalton and LSDalton

On behalf of all the authors, Hans Jørgen Aa. Jensen.
PS. A historical remark. In case you wonder why we use British spelling (licence, instead of license), this is simply because one of the authors insisted strongly on British spelling when we released Dalton the first time back in the 1990's, and it was not important to the rest of us.
