So we've got mixed reactions, mostly positive though, thankfully

You'll probably see the old blue design now again. If you want to use the new style per default do the following once:

1) Go to your UCP (User Control Panel).
2) Click on the "Board preferences"-tab.
3) Select "ratskep" from the dropdown-menu where it says "My board style:"
4) Click submit.

You're set

Cheers!

P.S. If you like the old, blue style more for whatever reason select "prosilver" and save your changes.
