videos on curl front page November 28 2014

The front page is now slightly modified to provide a fixed slot for the weekly (or so) videos made by Daniel.

Thanks page remake November 6 2014

The THANKS page,crediting all the people that have helped out in the project, has just gotten a little overhaul and now features a completely new look. We also made some extra efforts and removed some duplicate names from it, which explains why the amount of names went down somewhat.

Of course, if you think you are wrongly missing from the list of names, please tell us. We truly believe in giving proper credit!
