Hi, I try to duplicate this [http://arxiv.org/abs/0901.1458] article to ConTeXt. The original article was written in LaTeX. I have to troubles in this "duplication": - abstract: I "emulate" LaTeX abstract environment with \startnarrower ... \stopnarrower, as this [http://wiki.contextgarden.net/Article_Abstracts] wiki page suggests. But I see that the space between lines is much bigger in ConTeXt than LaTeX and that if we put $n^2$ for example in abstract, ConTeXt displays too big, as a normal text, instead of LaTeX where all is \small sized. - for the other hand, I want to put a "layer" as a footnote without markers. In the original article it begins with "Date: ...". How can I achieve that? - Finally, I want to put my name and title alternatively in the headertexts, in odd and even pages. How can I do that? Anyone could help me? Thanks a lot, Xan. PS: Please CC-me.
