Ok, I'm not going to debate this further with your persistent belief in having the comma...before this turns into another troll. This will be my last comment.
Look at it this way, both my example and MaSOuD's don't have the extra comma added at the end regardless of its workability. Why makes it unorthodox to be included? > and by the way, i dont need to give to you valid reasonsFor the record, there is none.
