I've added support for the CSW12 lexicon (and not a minute too soon!). I have NOT yet deleted CSW07 so you'll see daily challenges for both. I've also not moved any saved CSW07 lists to CSW12. Let me know if this is important to you.

If you're a Collins player should set your default lexicon to CSW12.

CSW12 words not in CSW07 have an additional '+' symbol in the definitions table like in Zyzzyva.

A couple extra tips:

• To set your default lexicon, click the wrench next to your username and then click Edit. (look at the top of your screen, next to the ugly Aerolith logo). You can set the default lexicon in the drop-down box. Don't forget to Save Profile.
• When loading a word list from your computer, make sure the correct lexicon is selected. If the file contains words not in this lexicon it will fail in an ugly way. I'll fix this when I have time to give a more gentle warning message.
