Well, for a time I was deleting them as well. But my presence on this particular website just got to annoying to continue with all the personal attacks and childishness that goes on here.
So, once in a while I will delete, fix formatting problems, answer questions, etc. but to devote that much time and energy to this particular website is not on my A list anymore. Participating here, at least at this time, has become a waste of my time and I have ceased to get anything out of it. If this is what a few people have set out to accomplish, then congratulations on your success. I hope it gets you far in life.
