Joe, you should know by now the forum guideline, "Your thread title should include all or part of the word/phrase being discussed."

Thanks for making me aware of the rule, I was not aware of it because I visit the forum occasionally now. Regarding the title not containing a part of the question asked or things related to it, I think it does if you include the word "sentence" in the title, which I think will fall under the "..part of.." category as just told by you. Still will try to be more careful next time.

Would now anyone like to answer my question, huh ?

Thanks
