Hello Thomas, I just noticed that I forgot to acknowledge your kind notice. Thanks for letting me know. I'm still trying to cope with this Minor edit thing. I can see my edits're not being considered as minor. From now on I will not check the box even with minor wordings, inserting references and so on, and I hope this will resolve the problem I created. In the meantime, I'll go ahead and study closely the minor edit guidelines. Thanks again.
