Sorry for the delay.

People who come visiting here may have noticed that recently I don't publish as many articles as I always did. Part of the reason is that I have been working hard on the preparation for my tutoring class. There are lots of things that need to be taken care of. At this point, for example, I am working on developing the website of the class that will have been accomplished by this Wednesday. In addition to that, some flyers will have to be created and sent out. Again, sorry for the delay but please come back frequently for checking out new stuff here. I will keep you posted from time to time as well.
