Dear Protein Puzzlers,

Another Monday brings new puzzles and software updates. Congratulations to our winners on puzzle 16 (Rosettamod, labraticmp3, mummiebrain, xavier, and zzaltz) and puzzle 17 (xavier, Rosettamod, hugothehermit, derwek, and Massakaparal). We have some new challenges for you in puzzles 18 and 19. Also, we have posted a software update that fixes several bugs (especially the save bug) and add more information about the current score and current tool.

Good luck on the new puzzles!
