Aaron: I'll ask Baha about the issue tracking... issue today. The code is hosted on Gerrit now, with a one-way mirror on this GitHub repo[1], which is not ideal from an openness/collaboration POV. For me, enabling easy issue tracking and pull requests is the most pressing issue. In the meantime, you can submit tasks through Phab. Add them to the Research board[2] and/or as subtasks of our Landing Page creation epic[3]. Not ideal, but at least you can capture things this way.
Federico: Translation via translatewiki would be very cool. We haven't prioritized this because, well, none of our on-wiki research team pages were ever translated, and this microsite is intended to supplement our on-wiki content, not replace it. But it sounds like a potential 'roadmap' kinda deal and I'll make sure to track it.
Iolanda: this is the landing page for the Wikimedia Foundation Research team[4], not for the international community of researchers who study Wiki[*]edia. It's also not the landing page for all researchers and research activities within the Wikimedia Foundation--just those of team members (and Aaron, whose Scoring Platform team is a kind of spin off/sibling of the research team).
