I have been working a lot with Cura recently as well, and I'm planning to release official Cura profiles for the Bukobot and Bukito in the near future.
We originally had open access to the wiki, but the volume of spam attempts was overwhelming and we had to lock it down. As is explained on the front page (now kind of hidden between things): If you would like to register to contribute to these pages, you will now need to email us at wiki[at]bukobot.com with a USERNAME, Your Real Name and Email. You will then get a return email with a random password to login. Sorry to have to do this, but we've had many spam bots and will keep this until we figure out a better solution. Thanks.
