The most common spelling mistake by cci members!

Hello Folks, I have noticed that there is one very common and popular spelling mistake most of the people here commit. The word is correctly spelled as 'DOUBT' but I find most of the members here spell it as "DOUGHT". There is no such word called "DOUGHT" in english dictionary. I hope many of you who were committing such grave mistake will take care of this now. Please don't take this otherwise. My intention is just to help. Regards Ashish Pathak
