Who is busy until Tuesday when he will most probably write a summary of the i18n mini summit which happened in my flat on Thursday and Friday, with Jose, Goba and me discussing and coding some i18n stuff (they did most of the coding, mostly I just provided some insight and space and corrected some pieces). Thanks for developmentseed for getting Jose here.
