How do I use the streak freeze. Do I purchase it "just in case"? Thanks for the help.
you purchase it and when you miss a day it dont reset your streak but then you must buy streak freeze again
Just remember though, if you use a streak freeze, you 'language specific' streak will drop to zero (the one you see when you hover your streak on your profile). The streak freeze only protects your 'overall streak' (the one you see on your profile without hovering, next to your flag on discussions and you earn lingots off of).
