“我今天没看你” emphasize on "Initiative to see".That means it is easy to recognize you, but i keep my sight away from you. And “我今天没看到你” emphasize on “accident”. That means i have not seen you today. Btw, I want to improve my english. I am working in Beijing. I wish we can help each other through chatting. My msn: [email protected]. Can you add me?

Usually, we donot say 我今天没看你，this sentance sounds a little weird. I don't know what it exactly mean by. i suppose it' s meaning depens on the context. 我今天没看到你 is a correct and smooth way to express" i haven't been seen u for a whole day". ^^

我今天没看你 ~ I have not looked at you today. 我今天不看你 ~ I will not look at you today. 我今天没看到你 ~ I have not seen you today or I did not see you today 没 here can be replaced by 没有， have not done sth I feel that 没 is used to describe some objective fact. while 不 is more subjective
