Since CASP is monopolizing the available puzzle spots, we'll be posting some non-CASP puzzles to try out (available in the Foldit Developer Preview, see below) in case you want a change of scenery (or a preview of what is to come).
The first such puzzle has just been posted, it's called "Flu Puzzle Testing" and will probably be the first non-CASP puzzle to be released once we have an opening in the puzzle queue.
These puzzles will not be scored and your solutions will not be analyzed.
I will add to this post anytime a new puzzle is added.
Q: How do I try out the Foldit Developer Preview?
A: Locate your Foldit data directory (see next question). Open the file options.txt and change the update_group variable from "main" to "devprev".
Q: Where can I find the Foldit data files?
A: The data files are in different places depending on your OS:
if you installed after 8/23/2011, they will be in your installation directory (the default is C:\Program Files\Foldit\ or C:\Program Files (x86)\Foldit\)
if you installed prior to 8/23/2011:
on Windows XP at C:\Documents and Settings\All Users\Application Data\Foldit\
on Windows 7 and Vista at C:\ProgramData\Foldit\
on a Mac, Ctrl-click on the app and choose "Show Package Contents, then go to Contents/Resources
on Linux, is is the Foldit directory
Q: I've had enough of the preview! How do I go back?
A: In your options.txt file (see first question), just change your update_group variable back to "main" from "devprev".
