About article

I see six articles pending for you. Does that sound correct? I think one of them is an old copy of your article about ref and out keywords. I don't know when the articles will be approved. Be patient and be assured that they are in progress. I do not approve articles and I don't know what the delay is. I can say that you might have to wait until Monday morning until someone has a chance to look at them. Unless you get an email message asking that you do something then it is just a matter of time.

There is no problem, its takes some time to get approved, edited and finally available to outside world.
