Hi!
You signed up on the Wikidata volunteers page as someone who's interested in coding. We've finally gotten things figured out and started with a few tasks. More will follow soon. You can find the current bugs/tasks here. If you decide to work on one of them please leave a note in the bug report saying so. Let me know if you have any questions :)
