@ CherryHarbey: I think only a moderator can close a thread, but don't worry about it.
I'm sure we have many threads here that are still going strong long after the initial topic/question was thoroughly addressed and the OPs forgot all about them. Sometimes they just take on lives of their own.
I don't think anyone will find you rude if you stop posting in this one, especially since you've stated that your question was answered. And somebody else may come along and have the same question and get an answer here, and then use this thread to post another question that someone else will post an answer to... and so it goes.
