What is this site called then, and why?

Indymedia + is the name of this new site, with contributions in English and soon also in Dutch. Indymedia +, also called i+, is not a part of the worldwide indymedia-network, but shares with it some objectives. It fights against the big power of corporate media and state media.
i+ will almost daily have new contributions in the near future. The names of the site just sound well, to the point. Indymedia + is not an independent media center, but the name of its founder, Rafa Grinfeld, has been connected to the indymedia network for years now, although he always just posted on it. “i+” as a name sounds a bit like i10, an international revue. Arthur Lehning was the editor of this avant-garde journal. Lehning (1899-2000) aligned himself with antimilitarists and libertarian socialists. In Amsterdam, he published the i10 International Revue from 1927 to 1929.
Within the pages of i10, Lehning collaborated with artists like Wassily Kandinsky and Piet Mondriaan. He also was supported by Walter Benjamin, Ernst Bloch, Max Netlau,
Alexander Berkman, Alexander Shapiro,...

Here is Lehning's obituary from the International Institute of Social History (IISH):

On January 1, 2000, Arthur Lehning died at his residence at Le Plessis, Indre (France). Born on October 23, 1899, he was 100 years old. Others will no doubt commemorate his life as an anarchist and anti-militarist, an essayist and the sole editor of the avant-garde journal i 10. He was, among many other things, a secretary of the anarcho-syndicalist International Working Men's Association in 1932-1935, at a time when the IWMA was closely involved in the revolutionary activities of the Spanish Confederacion Nacional del Trabajo.
At the International Institute of Social History, Lehning will be remembered as an important representative of its founding generation. In 1935 he was among the Institute's first staff, with a special responsibility for the South-European and Anarchist collections. From April 1939 all through WW II he was in charge of the Oxford branch of the IISH, to which the most sensitive archival records had been sent after the conclusion of the Munich Agreement. In 1957 he returned to the Institute as editor of the collected works of the Russian revolutionary, Mikhail Bakunin, published under the title Archives Bakounine. Some of his major scholarly articles were collected in From Buonarroti to Bakunin (1970).
A real internationalist, who lived in many countries and used to travel widely, Lehning always took a lively interest in political and cultural affairs that far outranged the traditional scope of the Institute. The IISH owes him deep gratitude for the tremendous work he has accomplished on its behalf.
