You mean you don't "hear" the "hua" sound. That's because there is no "hua" sound in "tight." It's spelled "tight" and it sounds just the same as "tite." Hope that helps. Hey... for real... feel free to come to me with spelling/grammar/pronunciation problems. Or am I just being a pain in the ass? I hope not.
Don't worry about the spelling thing, we were all really disappointed when you started using the Safari spell-checker...it's become part of your personality
