No we're not. Scientific papers can be added to the second part of the website easily and that's one of the reasons we're using LaTeX. We just need to add the right packages to make the website support math formulas and other things needed for scientific papers. We're just supporting the LaTeX command for footnotes right now but we'll keep on adding more.
